Secondary research: definition, methods, & examples.

19 min read This ultimate guide to secondary research helps you understand changes in market trends, customers buying patterns and your competition using existing data sources.

In situations where you’re not involved in the data gathering process ( primary research ), you have to rely on existing information and data to arrive at specific research conclusions or outcomes. This approach is known as secondary research.

In this article, we’re going to explain what secondary research is, how it works, and share some examples of it in practice.

What is secondary research?

Secondary research, also known as desk research, is a research method that involves compiling existing data sourced from a variety of channels . This includes internal sources (e.g.in-house research) or, more commonly, external sources (such as government statistics, organizational bodies, and the internet).

Secondary research comes in several formats, such as published datasets, reports, and survey responses , and can also be sourced from websites, libraries, and museums.

The information is usually free — or available at a limited access cost — and gathered using surveys , telephone interviews, observation, face-to-face interviews, and more.

When using secondary research, researchers collect, verify, analyze and incorporate it to help them confirm research goals for the research period.

As well as the above, it can be used to review previous research into an area of interest. Researchers can look for patterns across data spanning several years and identify trends — or use it to verify early hypothesis statements and establish whether it’s worth continuing research into a prospective area.

How to conduct secondary research

There are five key steps to conducting secondary research effectively and efficiently:

1.    Identify and define the research topic

First, understand what you will be researching and define the topic by thinking about the research questions you want to be answered.

Ask yourself: What is the point of conducting this research? Then, ask: What do we want to achieve?

This may indicate an exploratory reason (why something happened) or confirm a hypothesis. The answers may indicate ideas that need primary or secondary research (or a combination) to investigate them.

2.    Find research and existing data sources

If secondary research is needed, think about where you might find the information. This helps you narrow down your secondary sources to those that help you answer your questions. What keywords do you need to use?

Which organizations are closely working on this topic already? Are there any competitors that you need to be aware of?

Create a list of the data sources, information, and people that could help you with your work.

3.    Begin searching and collecting the existing data

Now that you have the list of data sources, start accessing the data and collect the information into an organized system. This may mean you start setting up research journal accounts or making telephone calls to book meetings with third-party research teams to verify the details around data results.

As you search and access information, remember to check the data’s date, the credibility of the source, the relevance of the material to your research topic, and the methodology used by the third-party researchers. Start small and as you gain results, investigate further in the areas that help your research’s aims.

4.    Combine the data and compare the results

When you have your data in one place, you need to understand, filter, order, and combine it intelligently. Data may come in different formats where some data could be unusable, while other information may need to be deleted.

After this, you can start to look at different data sets to see what they tell you. You may find that you need to compare the same datasets over different periods for changes over time or compare different datasets to notice overlaps or trends. Ask yourself: What does this data mean to my research? Does it help or hinder my research?

5.    Analyze your data and explore further

In this last stage of the process, look at the information you have and ask yourself if this answers your original questions for your research. Are there any gaps? Do you understand the information you’ve found? If you feel there is more to cover, repeat the steps and delve deeper into the topic so that you can get all the information you need.

If secondary research can’t provide these answers, consider supplementing your results with data gained from primary research. As you explore further, add to your knowledge and update your findings. This will help you present clear, credible information.

Primary vs secondary research

Unlike secondary research, primary research involves creating data first-hand by directly working with interviewees, target users, or a target market. Primary research focuses on the method for carrying out research, asking questions, and collecting data using approaches such as:

• Interviews (panel, face-to-face or over the phone)
• Questionnaires or surveys
• Focus groups

Using these methods, researchers can get in-depth, targeted responses to questions, making results more accurate and specific to their research goals. However, it does take time to do and administer.

Unlike primary research, secondary research uses existing data, which also includes published results from primary research. Researchers summarize the existing research and use the results to support their research goals.

Both primary and secondary research have their places. Primary research can support the findings found through secondary research (and fill knowledge gaps), while secondary research can be a starting point for further primary research. Because of this, these research methods are often combined for optimal research results that are accurate at both the micro and macro level.

Sources of Secondary Research

There are two types of secondary research sources: internal and external. Internal data refers to in-house data that can be gathered from the researcher’s organization. External data refers to data published outside of and not owned by the researcher’s organization.

Internal data

Internal data is a good first port of call for insights and knowledge, as you may already have relevant information stored in your systems. Because you own this information — and it won’t be available to other researchers — it can give you a competitive edge . Examples of internal data include:

• Database information on sales history and business goal conversions
• Information from website applications and mobile site data
• Customer-generated data on product and service efficiency and use
• Previous research results or supplemental research areas
• Previous campaign results

External data

External data is useful when you: 1) need information on a new topic, 2) want to fill in gaps in your knowledge, or 3) want data that breaks down a population or market for trend and pattern analysis. Examples of external data include:

• Government, non-government agencies, and trade body statistics
• Company reports and research
• Competitor research
• Public library collections
• Textbooks and research journals
• Media stories in newspapers
• Online journals and research sites

Three examples of secondary research methods in action

How and why might you conduct secondary research? Let’s look at a few examples:

1.    Collecting factual information from the internet on a specific topic or market

There are plenty of sites that hold data for people to view and use in their research. For example, Google Scholar, ResearchGate, or Wiley Online Library all provide previous research on a particular topic. Researchers can create free accounts and use the search facilities to look into a topic by keyword, before following the instructions to download or export results for further analysis.

This can be useful for exploring a new market that your organization wants to consider entering. For instance, by viewing the U.S Census Bureau demographic data for that area, you can see what the demographics of your target audience are , and create compelling marketing campaigns accordingly.

2.    Finding out the views of your target audience on a particular topic

If you’re interested in seeing the historical views on a particular topic, for example, attitudes to women’s rights in the US, you can turn to secondary sources.

Textbooks, news articles, reviews, and journal entries can all provide qualitative reports and interviews covering how people discussed women’s rights. There may be multimedia elements like video or documented posters of propaganda showing biased language usage.

By gathering this information, synthesizing it, and evaluating the language, who created it and when it was shared, you can create a timeline of how a topic was discussed over time.

3.    When you want to know the latest thinking on a topic

Educational institutions, such as schools and colleges, create a lot of research-based reports on younger audiences or their academic specialisms. Dissertations from students also can be submitted to research journals, making these places useful places to see the latest insights from a new generation of academics.

Information can be requested — and sometimes academic institutions may want to collaborate and conduct research on your behalf. This can provide key primary data in areas that you want to research, as well as secondary data sources for your research.

Advantages of secondary research

There are several benefits of using secondary research, which we’ve outlined below:

• Easily and readily available data – There is an abundance of readily accessible data sources that have been pre-collected for use, in person at local libraries and online using the internet. This data is usually sorted by filters or can be exported into spreadsheet format, meaning that little technical expertise is needed to access and use the data.
• Faster research speeds – Since the data is already published and in the public arena, you don’t need to collect this information through primary research. This can make the research easier to do and faster, as you can get started with the data quickly.
• Low financial and time costs – Most secondary data sources can be accessed for free or at a small cost to the researcher, so the overall research costs are kept low. In addition, by saving on preliminary research, the time costs for the researcher are kept down as well.
• Secondary data can drive additional research actions – The insights gained can support future research activities (like conducting a follow-up survey or specifying future detailed research topics) or help add value to these activities.
• Secondary data can be useful pre-research insights – Secondary source data can provide pre-research insights and information on effects that can help resolve whether research should be conducted. It can also help highlight knowledge gaps, so subsequent research can consider this.
• Ability to scale up results – Secondary sources can include large datasets (like Census data results across several states) so research results can be scaled up quickly using large secondary data sources.

Disadvantages of secondary research

The disadvantages of secondary research are worth considering in advance of conducting research :

• Secondary research data can be out of date – Secondary sources can be updated regularly, but if you’re exploring the data between two updates, the data can be out of date. Researchers will need to consider whether the data available provides the right research coverage dates, so that insights are accurate and timely, or if the data needs to be updated. Also, fast-moving markets may find secondary data expires very quickly.
• Secondary research needs to be verified and interpreted – Where there’s a lot of data from one source, a researcher needs to review and analyze it. The data may need to be verified against other data sets or your hypotheses for accuracy and to ensure you’re using the right data for your research.
• The researcher has had no control over the secondary research – As the researcher has not been involved in the secondary research, invalid data can affect the results. It’s therefore vital that the methodology and controls are closely reviewed so that the data is collected in a systematic and error-free way.
• Secondary research data is not exclusive – As data sets are commonly available, there is no exclusivity and many researchers can use the same data. This can be problematic where researchers want to have exclusive rights over the research results and risk duplication of research in the future.

When do we conduct secondary research?

Now that you know the basics of secondary research, when do researchers normally conduct secondary research?

It’s often used at the beginning of research, when the researcher is trying to understand the current landscape . In addition, if the research area is new to the researcher, it can form crucial background context to help them understand what information exists already. This can plug knowledge gaps, supplement the researcher’s own learning or add to the research.

Secondary research can also be used in conjunction with primary research. Secondary research can become the formative research that helps pinpoint where further primary research is needed to find out specific information. It can also support or verify the findings from primary research.

You can use secondary research where high levels of control aren’t needed by the researcher, but a lot of knowledge on a topic is required from different angles.

Secondary research should not be used in place of primary research as both are very different and are used for various circumstances.

Questions to ask before conducting secondary research

Before you start your secondary research, ask yourself these questions:

• Is there similar internal data that we have created for a similar area in the past?

If your organization has past research, it’s best to review this work before starting a new project. The older work may provide you with the answers, and give you a starting dataset and context of how your organization approached the research before. However, be mindful that the work is probably out of date and view it with that note in mind. Read through and look for where this helps your research goals or where more work is needed.

• What am I trying to achieve with this research?

When you have clear goals, and understand what you need to achieve, you can look for the perfect type of secondary or primary research to support the aims. Different secondary research data will provide you with different information – for example, looking at news stories to tell you a breakdown of your market’s buying patterns won’t be as useful as internal or external data e-commerce and sales data sources.

• How credible will my research be?

If you are looking for credibility, you want to consider how accurate the research results will need to be, and if you can sacrifice credibility for speed by using secondary sources to get you started. Bear in mind which sources you choose — low-credibility data sites, like political party websites that are highly biased to favor their own party, would skew your results.

• What is the date of the secondary research?

When you’re looking to conduct research, you want the results to be as useful as possible , so using data that is 10 years old won’t be as accurate as using data that was created a year ago. Since a lot can change in a few years, note the date of your research and look for earlier data sets that can tell you a more recent picture of results. One caveat to this is using data collected over a long-term period for comparisons with earlier periods, which can tell you about the rate and direction of change.

• Can the data sources be verified? Does the information you have check out?

If you can’t verify the data by looking at the research methodology, speaking to the original team or cross-checking the facts with other research, it could be hard to be sure that the data is accurate. Think about whether you can use another source, or if it’s worth doing some supplementary primary research to replicate and verify results to help with this issue.

Types of Secondary Research Methods with Examples

Secondary research methods offer a range of approaches for leveraging existing data, each providing value in extracting insights relevant to various business and academic needs. Understanding the unique advantages of each method can guide researchers in choosing the most appropriate approach for their specific objectives.

Literature Reviews

Literature reviews synthesize existing research and publications to identify trends, gaps, and consensus within a field of study. This method provides a comprehensive overview of what is already known about a topic, saving time and resources by building on existing knowledge rather than starting from scratch.

Real-World Example : A marketing firm conducting a literature review on consumer behavior in the digital age might uncover a trend towards increased mobile shopping. This insight leads to a strategic recommendation for a retail client to prioritize mobile app development and optimize their online store for mobile users, directly impacting the client's digital marketing strategy.

Data Mining

Data mining involves analyzing large sets of data to discover patterns, correlations, or trends that are not immediately apparent. This method can uncover hidden insights from the data that businesses can use to inform decision-making, such as identifying new market opportunities or optimizing operational efficiencies.

Real-World Example : Through data mining of customer purchase histories and online behavior data, a retail company identifies a previously unnoticed correlation between the purchase of certain products and the time of year. Utilizing this insight, the company adjusts its inventory levels and marketing campaigns seasonally, significantly boosting sales and customer satisfaction.

Meta-Analysis

Meta-analysis aggregates and systematically analyzes results from multiple studies to draw general conclusions about a research question. This method provides a high level of evidence by combining findings, offering a powerful tool for making informed decisions based on a broader range of data than any single study could provide.

Real-World Example : A pharmaceutical company uses meta-analysis to combine findings from various clinical trials of a new drug. The meta-analysis reveals a statistically significant benefit of the drug that was not conclusive in individual studies. This insight supports the company's application for regulatory approval and guides the development of marketing strategies targeting specific patient demographics.

Data Analysis

Secondary data analysis applies statistical techniques to analyze existing datasets, offering a cost-effective way to gain insights without the need for new data collection. This method can identify trends, patterns, and relationships that inform strategic planning and decision-making.

Real-World Example : An investment firm analyzes historical economic data and stock market trends using secondary data analysis. They identify a recurring pattern preceding market downturns. By applying this insight to their investment strategy, the firm successfully mitigates risk and enhances portfolio performance for their clients.

Content Analysis

Content analysis systematically examines the content of communication mediums to understand messages, themes, or biases . This qualitative method can reveal insights into public opinion, media representation, and communication strategies, offering valuable information for marketing, public relations, and media strategies.

Real-World Example : A technology company employs content analysis to review online customer reviews and social media mentions of its products. The analysis uncovers a common concern among customers about the usability of a product feature. Responding to this insight, the company revises its product design and launches a targeted communication campaign to address the concerns, improving customer satisfaction and brand perception.

Historical Research

Historical research examines past records and documents to understand historical contexts and trends, offering insights that can inform future predictions, strategy development, and understanding of long-term changes. This method is particularly valuable for understanding the evolution of markets, industries, or consumer behaviors over time.

Real-World Example : A consultancy specializing in sustainable business practices conducts historical research into the adoption of green technologies in the automotive industry. The research identifies key drivers and barriers to adoption over the decades. Leveraging these insights, the consultancy advises new green tech startups on strategies to overcome market resistance and capitalize on drivers of adoption, significantly impacting their market entry strategy.

Each of these secondary research methods provides distinct advantages and can yield valuable insights for businesses and researchers. By carefully selecting and applying the most suitable method(s), organizations can enhance their understanding of complex issues, inform strategic decisions, and achieve competitive advantage.

Primary vs. Secondary Sources | Difference & Examples

Published on June 20, 2018 by Raimo Streefkerk . Revised on May 31, 2023.

When you do research, you have to gather information and evidence from a variety of sources.

Primary sources provide raw information and first-hand evidence. Examples include interview transcripts, statistical data, and works of art. Primary research gives you direct access to the subject of your research.

Secondary sources provide second-hand information and commentary from other researchers. Examples include journal articles, reviews, and academic books . Thus, secondary research describes, interprets, or synthesizes primary sources.

Primary sources are more credible as evidence, but good research uses both primary and secondary sources.

A primary source is anything that gives you direct evidence about the people, events, or phenomena that you are researching. Primary sources will usually be the main objects of your analysis.

If you are researching the past, you cannot directly access it yourself, so you need primary sources that were produced at the time by participants or witnesses (e.g. letters, photographs, newspapers ).

If you are researching something current, your primary sources can either be qualitative or quantitative data that you collect yourself (e.g. through interviews , surveys , experiments ) or sources produced by people directly involved in the topic (e.g. official documents or media texts).

A secondary source is anything that describes, interprets, evaluates, or analyzes information from primary sources. Common examples include:

• Books , articles and documentaries that synthesize information on a topic
• Synopses and descriptions of artistic works
• Encyclopedias and textbooks that summarize information and ideas
• Reviews and essays that evaluate or interpret something

When you cite a secondary source, it’s usually not to analyze it directly. Instead, you’ll probably test its arguments against new evidence or use its ideas to help formulate your own.

Examples of sources that can be primary or secondary

A secondary source can become a primary source depending on your research question . If the person, context, or technique that produced the source is the main focus of your research, it becomes a primary source.

Documentaries

If you are researching the causes of World War II, a recent documentary about the war is a secondary source . But if you are researching the filmmaking techniques used in historical documentaries, the documentary is a primary source .

If your paper is about the novels of Toni Morrison, a magazine review of one of her novels is a secondary source . But if your paper is about the critical reception of Toni Morrison’s work, the review is a primary source .

Newspaper articles

If your aim is to analyze the government’s economic policy, a newspaper article about a new policy is a secondary source . But if your aim is to analyze media coverage of economic issues, the newspaper article is a primary source .

To determine if something can be used as a primary or secondary source in your research, there are some simple questions you can ask yourself:

• Does this source come from someone directly involved in the events I’m studying (primary) or from another researcher (secondary)?
• Am I interested in evaluating the source itself (primary) or only using it for background information (secondary)?
• Does the source provide original information (primary) or does it comment upon information from other sources (secondary)?

Most research uses both primary and secondary sources. They complement each other to help you build a convincing argument. Primary sources are more credible as evidence, but secondary sources show how your work relates to existing research. Tertiary sources are often used in the first, exploratory stage of research.

What do you use primary sources for?

Primary sources are the foundation of original research. They allow you to:

• Make new discoveries
• Provide credible evidence for your arguments
• Give authoritative information about your topic

If you don’t use any primary sources, your research may be considered unoriginal or unreliable.

What do you use secondary sources for?

Secondary sources are good for gaining a full overview of your topic and understanding how other researchers have approached it. They often synthesize a large number of primary sources that would be difficult and time-consuming to gather by yourself. They allow you to:

• Gain background information on the topic
• Support or contrast your arguments with other researchers’ ideas
• Gather information from primary sources that you can’t access directly (e.g. private letters or physical documents located elsewhere)

When you conduct a literature review or meta analysis, you can consult secondary sources to gain a thorough overview of your topic. If you want to mention a paper or study that you find cited in a secondary source, seek out the original source and cite it directly.

Remember that all primary and secondary sources must be cited to avoid plagiarism . You can use Scribbr’s free citation generator to do so!

Common examples of primary sources include interview transcripts , photographs, novels, paintings, films, historical documents, and official statistics.

Anything you directly analyze or use as first-hand evidence can be a primary source, including qualitative or quantitative data that you collected yourself.

Common examples of secondary sources include academic books, journal articles , reviews, essays , and textbooks.

Anything that summarizes, evaluates or interprets primary sources can be a secondary source. If a source gives you an overview of background information or presents another researcher’s ideas on your topic, it is probably a secondary source.

To determine if a source is primary or secondary, ask yourself:

• Was the source created by someone directly involved in the events you’re studying (primary), or by another researcher (secondary)?
• Does the source provide original information (primary), or does it summarize information from other sources (secondary)?
• Are you directly analyzing the source itself (primary), or only using it for background information (secondary)?

Some types of source are nearly always primary: works of art and literature, raw statistical data, official documents and records, and personal communications (e.g. letters, interviews ). If you use one of these in your research, it is probably a primary source.

Primary sources are often considered the most credible in terms of providing evidence for your argument, as they give you direct evidence of what you are researching. However, it’s up to you to ensure the information they provide is reliable and accurate.

Always make sure to properly cite your sources to avoid plagiarism .

A fictional movie is usually a primary source. A documentary can be either primary or secondary depending on the context.

If you are directly analyzing some aspect of the movie itself – for example, the cinematography, narrative techniques, or social context – the movie is a primary source.

If you use the movie for background information or analysis about your topic – for example, to learn about a historical event or a scientific discovery – the movie is a secondary source.

Whether it’s primary or secondary, always properly cite the movie in the citation style you are using. Learn how to create an MLA movie citation or an APA movie citation .

Articles in newspapers and magazines can be primary or secondary depending on the focus of your research.

In historical studies, old articles are used as primary sources that give direct evidence about the time period. In social and communication studies, articles are used as primary sources to analyze language and social relations (for example, by conducting content analysis or discourse analysis ).

If you are not analyzing the article itself, but only using it for background information or facts about your topic, then the article is a secondary source.

In the social sciences, a secondary source is usually a scholar book, journal article, or digital or print document that was created by someone who did not directly experience or participate in the events or conditions under investigation. Secondary sources are not evidence per se, but rather, provide an interpretation, analysis, or commentary derived from the content of primary source materials and/or other secondary sources.

Value of Secondary Sources

To do research, you must cite research. Primary sources do not represent research per se, but only the artifacts from which most research is derived. Therefore, the majority of sources in a literature review are secondary sources that present research findings, analysis, and the evaluation of other researcher's works.

Reviewing secondary source material can be of valu e in improving your overall research paper because secondary sources facilitate the communication of what is known about a topic. This literature also helps you understand the level of uncertainty about what is currently known and what additional information is needed from further research. It is important to note, however, that secondary sources are not the subject of your analysis. Instead, they represent various opinions, interpretations, and arguments about the research problem you are investigating--opinions, interpretations, and arguments with which you may either agree or disagree with as part of your own analysis of the literature.

Examples of secondary sources you could review as part of your overall study include:     * Bibliographies [also considered tertiary]     * Biographical works     * Books, other than fiction and autobiography     * Commentaries, criticisms     * Dictionaries, Encyclopedias [also considered tertiary]     * Histories     * Journal articles [depending on the discipline, they can be primary]     * Magazine and newspaper articles [this distinction varies by discipline]     * Textbooks [also considered tertiary]     * Web site [also considered primary]

Secondary Research: Definition, Methods and Examples.

In the world of research, there are two main types of data sources: primary and secondary. While primary research involves collecting new data directly from individuals or sources, secondary research involves analyzing existing data already collected by someone else. Today we’ll discuss secondary research.

One common source of this research is published research reports and other documents. These materials can often be found in public libraries, on websites, or even as data extracted from previously conducted surveys. In addition, many government and non-government agencies maintain extensive data repositories that can be accessed for research purposes.

LEARN ABOUT: Research Process Steps

While secondary research may not offer the same level of control as primary research, it can be a highly valuable tool for gaining insights and identifying trends. Researchers can save time and resources by leveraging existing data sources while still uncovering important information.

What is Secondary Research: Definition

Secondary research is a research method that involves using already existing data. Existing data is summarized and collated to increase the overall effectiveness of the research.

One of the key advantages of secondary research is that it allows us to gain insights and draw conclusions without having to collect new data ourselves. This can save time and resources and also allow us to build upon existing knowledge and expertise.

When conducting secondary research, it’s important to be thorough and thoughtful in our approach. This means carefully selecting the sources and ensuring that the data we’re analyzing is reliable and relevant to the research question . It also means being critical and analytical in the analysis and recognizing any potential biases or limitations in the data.

LEARN ABOUT: Level of Analysis

Secondary research is much more cost-effective than primary research , as it uses already existing data, unlike primary research, where data is collected firsthand by organizations or businesses or they can employ a third party to collect data on their behalf.

LEARN ABOUT: Data Analytics Projects

Secondary Research Methods with Examples

Secondary research is cost-effective, one of the reasons it is a popular choice among many businesses and organizations. Not every organization is able to pay a huge sum of money to conduct research and gather data. So, rightly secondary research is also termed “ desk research ”, as data can be retrieved from sitting behind a desk.

The following are popularly used secondary research methods and examples:

1. Data Available on The Internet

One of the most popular ways to collect secondary data is the internet. Data is readily available on the internet and can be downloaded at the click of a button.

This data is practically free of cost, or one may have to pay a negligible amount to download the already existing data. Websites have a lot of information that businesses or organizations can use to suit their research needs. However, organizations need to consider only authentic and trusted website to collect information.

2. Government and Non-Government Agencies

Data for secondary research can also be collected from some government and non-government agencies. For example, US Government Printing Office, US Census Bureau, and Small Business Development Centers have valuable and relevant data that businesses or organizations can use.

There is a certain cost applicable to download or use data available with these agencies. Data obtained from these agencies are authentic and trustworthy.

3. Public Libraries

Public libraries are another good source to search for data for this research. Public libraries have copies of important research that were conducted earlier. They are a storehouse of important information and documents from which information can be extracted.

The services provided in these public libraries vary from one library to another. More often, libraries have a huge collection of government publications with market statistics, large collection of business directories and newsletters.

4. Educational Institutions

Importance of collecting data from educational institutions for secondary research is often overlooked. However, more research is conducted in colleges and universities than any other business sector.

The data that is collected by universities is mainly for primary research. However, businesses or organizations can approach educational institutions and request for data from them.

5. Commercial Information Sources

Local newspapers, journals, magazines, radio and TV stations are a great source to obtain data for secondary research. These commercial information sources have first-hand information on economic developments, political agenda, market research, demographic segmentation and similar subjects.

Businesses or organizations can request to obtain data that is most relevant to their study. Businesses not only have the opportunity to identify their prospective clients but can also know about the avenues to promote their products or services through these sources as they have a wider reach.

Key Differences between Primary Research and Secondary Research

Understanding the distinction between primary research and secondary research is essential in determining which research method is best for your project. These are the two main types of research methods, each with advantages and disadvantages. In this section, we will explore the critical differences between the two and when it is appropriate to use them.

How to Conduct Secondary Research?

We have already learned about the differences between primary and secondary research. Now, let’s take a closer look at how to conduct it.

Secondary research is an important tool for gathering information already collected and analyzed by others. It can help us save time and money and allow us to gain insights into the subject we are researching. So, in this section, we will discuss some common methods and tips for conducting it effectively.

Here are the steps involved in conducting secondary research:

1. Identify the topic of research: Before beginning secondary research, identify the topic that needs research. Once that’s done, list down the research attributes and its purpose.

2. Identify research sources: Next, narrow down on the information sources that will provide most relevant data and information applicable to your research.

3. Collect existing data: Once the data collection sources are narrowed down, check for any previous data that is available which is closely related to the topic. Data related to research can be obtained from various sources like newspapers, public libraries, government and non-government agencies etc.

4. Combine and compare: Once data is collected, combine and compare the data for any duplication and assemble data into a usable format. Make sure to collect data from authentic sources. Incorrect data can hamper research severely.

4. Analyze data: Analyze collected data and identify if all questions are answered. If not, repeat the process if there is a need to dwell further into actionable insights.

Advantages of Secondary Research

Secondary research offers a number of advantages to researchers, including efficiency, the ability to build upon existing knowledge, and the ability to conduct research in situations where primary research may not be possible or ethical. By carefully selecting their sources and being thoughtful in their approach, researchers can leverage secondary research to drive impact and advance the field. Some key advantages are the following:

1. Most information in this research is readily available. There are many sources from which relevant data can be collected and used, unlike primary research, where data needs to collect from scratch.

2. This is a less expensive and less time-consuming process as data required is easily available and doesn’t cost much if extracted from authentic sources. A minimum expenditure is associated to obtain data.

3. The data that is collected through secondary research gives organizations or businesses an idea about the effectiveness of primary research. Hence, organizations or businesses can form a hypothesis and evaluate cost of conducting primary research.

4. Secondary research is quicker to conduct because of the availability of data. It can be completed within a few weeks depending on the objective of businesses or scale of data needed.

As we can see, this research is the process of analyzing data already collected by someone else, and it can offer a number of benefits to researchers.

Disadvantages of Secondary Research

On the other hand, we have some disadvantages that come with doing secondary research. Some of the most notorious are the following:

1. Although data is readily available, credibility evaluation must be performed to understand the authenticity of the information available.

2. Not all secondary data resources offer the latest reports and statistics. Even when the data is accurate, it may not be updated enough to accommodate recent timelines.

3. Secondary research derives its conclusion from collective primary research data. The success of your research will depend, to a greater extent, on the quality of research already conducted by primary research.

LEARN ABOUT: 12 Best Tools for Researchers

In conclusion, secondary research is an important tool for researchers exploring various topics. By leveraging existing data sources, researchers can save time and resources, build upon existing knowledge, and conduct research in situations where primary research may not be feasible.

There are a variety of methods and examples of secondary research, from analyzing public data sets to reviewing previously published research papers. As students and aspiring researchers, it’s important to understand the benefits and limitations of this research and to approach it thoughtfully and critically. By doing so, we can continue to advance our understanding of the world around us and contribute to meaningful research that positively impacts society.

Primary and secondary sources: what are they and why do I need them?

What are the main differences between primary and secondary sources?

Why do i need to use both primary and secondary sources in my research, examples of primary and secondary sources, frequently asked questions about primary and secondary sources, related articles.

Primary and secondary sources are the two main types of source materials that you will use for your research project. They are both important and needed for your project. Whether you are going to use more primary or more secondary sources depends on your academic level - undergrad, postgrad, or professional.

Both types of sources have importance and merits of their own, but they are also immensely different. This guide will help you understand the differences. If you want to learn even more about both source types separately, where and how you can access them, and when and how to use them, check out the links below:

➡️  What is a primary source?

➡️  What is a secondary source?

The main difference between primary and secondary sources is that primary sources are contemporary.

Primary sources are original and originated from the event they refer to. They are not reviews, analyses, or critiques of events that occurred in the past. They are first-hand information.

Secondary sources are summaries, critiques, opinions, and analyses. They are written by people who did not witness, or have any direct part to play in the event they are describing. The information they contain is based on primary sources and is the author’s interpretation of the event/subject they are covering.

Using both types of sources adds to the merit of your research. By including references to secondary sources , you are showing that you have truly engaged with your research topic. You are providing extra information and displaying a well-rounded approach to your topic. You are not relying solely on the work of one person, or one institution, for your analysis to be based upon. You are reading broadly and contextually.

Likewise, including primary source references in your research shows that you are also going back to the roots. You are looking at the event or object as it happened, without being able to teleport through time and space. A primary source is vital because it will enable you to make your own judgement on an event or object. Secondary sources are always biased, in one sense or another, so engaging with the primary source yourself allows you to view the topic objectively.

Primary and secondary sources complement each other - looking at both can give you a deeper understanding of each. A primary source can help you to evaluate a secondary source - you will notice aspects of it which the author dismisses, or washes over in their discussion. Likewise, a secondary source can tell you about current trends in research and analysis, while providing you with a broad overview or summary of an extended period of time, or the works of an artist.

We have put together a list of examples of primary and secondary sources by fields of study. It will help you identify the nature of your source.

Primary sources are original and originated from the event they refer to. They are not reviews, analyses, or critiques of events that occurred in the past. They are first-hand information. For a more detailed description of what a primary source is, where you can access them, and why you need to use them, see this article about primary sources .

Secondary sources are summaries, critiques, opinions, and analyses. They are written by people who did not witness, or have any direct part to play in the event they are describing. The information they contain is based on primary sources, and is the author’s interpretation of the event/subject they are covering. See this article about secondary sources for further information.

Some examples of primary sources are: Poems, diaries, letters, paintings, government records, maps, interviews (transcribed or recorded), photographs, newspaper articles, results of experiments, case studies, results of clinical trials, minutes of meetings, and proceedings of conferences

Some examples of secondary sources are: Biographies, histories, reviews, encyclopaedias, literary criticism, discussions of importance, analysis of clinical trials, and reviews of results.

The one main difference between primary and secondary sources is that primary sources are contemporary and secondary sources are not.

Secondary Sources: ALRs, Encyclopedias, Law Reviews, Restatements, & Treatises

Legal encyclopedias, law review articles, american law reports, restatement drafts, getting help, introduction.

Secondary sources are a great place to begin your research . Although the primary sources of law--case law, statutes, and regulations--establish the law on a given topic, it is often difficult to quickly locate answers in them. Secondary sources often explain legal principles more thoroughly than a single case or statute, so using them can help you save time . Secondary sources also help you avoid unnecessary research, since you're tapping into work that someone else has already done on an issue.

Secondary sources include:

• Legal encyclopedias
• American Law Reports (ALR)
• Law review articles

Restatements

Secondary sources are particularly useful for:

• Learning the basics of a particular area of law
• Understanding key terms of art in an area
• Identifying essential cases and statutes

This guide provides a basic overview of each source, including their strengths and why you might use them, as well as tips on finding, using, and citing them.

This guide is based on material written by Deanna Barmakian.

Intro to Legal Encyclopedias

Legal encyclopedias contain brief, broad summaries of legal topics, providing introductions to legal topics and explaining relevant terms of art.They also provide citations to relevant primary law and sometimes give citations to relevant major law review articles.

There are two main legal encyclopedias in the United States that are national in scope. They are useful, but not well-suited for jurisdiction specific research.

State legal encyclopedias provide background and explanations of state legal topics. Not every state has a legal encyclopedia. Depth of coverage and quality vary. State encyclopedia articles are updated irregularly.

Electronic versions of the encyclopedias are updated directly. If using a print encyclopedia, always remember to check the pocket parts for any updates.

National Legal Encyclopedias

• American Jurisprudence 2d (AmJur) Reading Room KF 154.A42 Am Jur 2d articles summarize broad principles of U.S. law and provide citations to cases, statutes, rules, forms, and A.L.R. annotations. A six-volume general index is located at KF 154.A42. Topical indexes are located in the last volume of every topic.
• American Jurisprudence Available on Lexis
• American Jurisprudence on Westlaw
• Corpus Juris Secundum (CJS) Reading Room KF 154.C56 This 152-volume set is arranged into approximately 400 topics. Articles within topics begin with a general rule of law and are followed by the exceptions and qualifications to that general rule. A four-volume general index is located at KF 154.C56. There are also individual indexes for each major topic.
• Corpus Juris Secundum on Westlaw CJS is not available on Lexis.

State Legal Encyclopedias

Legal encyclopedias are listed alphabetically by state. Electronic versions are included only if they are comprehensive in scope.

For a few states, Westlaw offers a practice series that contains selective coverage of state law, usually covering a few major topics and information useful to litigators. To find them, browse the Westlaw directory by U.S. State Materials > Other U.S. States > State name >  Forms, Treatises, CLEs, and Other Practice Materials, then browse the page for "practice series."

Intro to Treatises

Treatises , not to be confused with treaties , are book-length expositions on the law as it pertains to a particular subject. Treatises may be scholarly in nature, such as Blackstone’s Commentaries on the Law , or they may be geared toward a legal practitioner, such as a manual or handbook.

A legal treatise may be a short, single volume or a large, multivolume set. Many are available electronically as well as in print. Different kinds of treatises have different purposes:

Legal hornbooks are designed as teaching tools for law students. Hornbooks provide more detailed treatments of particular areas of law than an encyclopedia or ALR entry. They generally contain summaries of landmark cases and other useful details.

Nutshells provide an overview of a legal topic without the detailed analysis or extensive case referencing found in other treatises.

Some treatises are designed to serve as practitioners’ tools. These works tend to address realistic legal problems and often provide useful features for practicing lawyers, such as forms and tables.

Looseleaf services are an example of treatises designed to serve as tools for practitioners. Such works address realistic legal problems and often provide useful features for practicing lawyers, such as forms and tables. Looseleaf services are frequently supplemented treatises--hence the looseleaf binder format that enables single pages to be easily updated without republishing the entire volume--that often contain primary legal sources and finding aids in addition to secondary analytical material, making them an invaluable resource if one exists for your topic.

Still other treatises are designed to serve as self-help publications for the public, such as those published by Nolo Press .

Finding treatises

There are several ways to locate legal treatises:

• Use the HLS Library Guide to Legal Treatises by Subject for librarian-recommended treatises in many areas of law
• Do a keyword or subject search in Hollis , Hollis Classic , or another library catalog . Use the expanded search or facets to limit your search to the law school library.
• Ask a research librarian to help you locate treatises on your topic
• Consult reference sources that review treatises by subject such as:

The Legal Information Buyer's Guide and Reference Manual by Ken Svengalis Legal Information: How to Find It, How to Use It by Kent C. Olson (note: this guide does not include single volume works) Legal Looseleafs in Print by Arlene Eis

Using treatises

Using legal treatises is like using any non-law book with a few special advisories.

First, as with any book, use the table of contents and the index to quickly locate relevant sections .

Second, remember that for a publication to provide reliable coverage of contemporary issues, it must be updated regularly and accurately to reflect any changes in the law . Updating may happen through the addition of pocket parts (which are usually tucked in a pocket in the back cover of a volume), by updated pages in a looseleaf, or periodic republication or an entire volume. Researchers should always make sure they are working with the most current edition of the treatise and be sure to consult pocket parts.

Third, while many treatises are still only available in print, more treatises are becoming available online . For example, major treatises on insurance law are available in both Lexis and Westlaw. Electronic versions of treatises allow for full text searching, which can be valuable for research. For more focused search results, consider narrowing your search to relevant sections, if possible. In many cases, you can still access the tables of contents and indexes to help locate chapters or sections of interest.

Remember that you can (and should!) check to see how current the electronic text is by clicking the I link next to the title of the treatise to see how regularly it is updated and when the last update took place.

Intro to Law Review Articles

Law review or journal articles are another great secondary source for legal research, valuable for the depth in which they analyze and critique legal topics, as well as their extensive references to other sources, including primary sources.

Law reviews are scholarly publications, usually edited by law students in conjunction with faculty members. They contain both lengthy articles and shorter essays by professors and lawyers, as well as comments, notes, or developments in the law written by students. Law review articles often focus on new or emerging areas of law and they can offer more critical commentary than a legal encyclopedia or ALR entry .

Some law reviews are dedicated to a particular topic, such as gender and the law or environmental law, and will include in their contents the proceedings of a wide range of panels and symposia on timely legal issues.

Sources of full text law review articles

These resources all provide comprehensive coverage of United States law reviews, and allow you to search the full text of the articles that they index.

• Bloomberg Law Bloomberg Law is available to all HLS students, faculty, and staff. Register with your HLS email address. Law reviews are included in Bloomberg Law's selection of secondary sources.
• HeinOnline Law Journal Library Database of full text, PDF law review articles; use advanced search to search by topic or search specific titles. HeinOnline is the most comprehensive law review articles database, as coverage begins with the first issue of each journal.
• LexisNexis U.S. Law Reviews and Journals, Combined Combined full text database of United States Law Reviews and Bar Journals. Coverage begins in 1982; regular updates as received from publishers. Lexis also contains databases for Canadian law reviews articles and law review articles by jurisdiction and topic.
• Westlaw Journals & Law Reviews Journals and Law Reviews contains full text documents from law reviews and CLE materials from U.S. and Canadian based publications. Coverage varies by publication with most going back to the 1980s or 1990s.

Indexes to law reviews and journals

These resources only index articles, usually by author, title, keywords, and subject; you will have to find the full text separately. However, they provide additional ways of searching, including taking advantage of subject indexing by expert librarians, and they enable finding material that may not be found in full text databases. In most cases, there will be a link to find the article you desire at Harvard. If we do not own the journal in question, you may request the article via interlibrary loan .

• Current Index to Legal Periodicals A weekly publication by the University of Washington Library, CILP indexes the most recent law review and journal publications by subject as well as provides the tables of contents of the journals indexed. Also available on Westlaw and in print in the reference room at K 33 .C86.
• Index to Foreign Legal Periodicals IFLP indexes legal literature worldwide, covering all forms of foreign law, including comparative law and legal systems, such as Islamic law; socialist law; public and private international law; and transnational commercial law.

Also available in print in the reference room at KD 59 .L44.

Working Paper Repositories

Working papers are an additional source of secondary analysis. They are frequently draft or pre-publication versions of law review articles, though you will also find published versions of articles in these databases. When citing or relying on a draft paper, be sure to carefully check its citations and request the author's permission before citing.

• SSRN Legal Scholarship Network Contains both published and working papers by law faculty, as well as scholars working in the fields of accounting, economics, financial economics, and management. Search by author and by title and abstract keywords. Most papers are available for download in pdf format.
• BePress Legal Repository Contains approximately 3000 articles and papers by law faculty.

Intro to ALR

American Law Reports (frequently abbreviated and referred to as ALR) contains in-depth articles on narrow topics of the law. ALR articles, called annotations, provide background, analysis, and citations to relevant cases, statutes, law review articles, and other annotations .

ALR is published in series:

• two series under its original title Lawyers Reports Annotated
• eight ALR series, one through six
• two federal series

ALR annotations are not jurisdiction specific. Each annotation contains a Table of Jurisdictions to help you find relevant cases within specific states. In the federal series, the Table of Jurisdictions directs you to cases by circuit.

All ALR series continue to be updated, though not on a regular schedule. When using the set in print, always check the pocket parts for updates. ALR is also available in both Lexis and Westlaw, and the electronic versions incorporate updates into the text. ALR annotations can also be completely superceded by more recent annotations. Electronic versions will provide referrals to the superceding annotations, but in print, you should check the History Table at the end of the ALR Index to verify that your annotation has not been superceded.

Find relevant annotations by using the print indices or searching the ALR databases in Lexis or Westlaw. When using ALR electronically, it is most efficient to look for your terms in the titles of the annotations, since their titles are specific, and reflect their contents.

Finding ALR in print and online

• ALR on Westlaw Contains the full text of the annotations included in the First, Second, Third, Fourth, Fifth, Sixth, Federal, and Federal Second series of American Law Reports (ALR) and the Index to Annotations covering these series. Because West publishes ALR, this is the most comprehensive electronic version.

• The ALR Index is located in the Reading Room at KF 132.2.I53. It covers annotations written since 1948.
• The ALR Quick Index is located in the Reading Room at KF 132.6.A543. It covers major annotations from the ALR 3d series to the present.

How to Cite ALR Annotations

Intro to Restatements

Restatements are highly regarded distillations of common law . They are prepared by the American Law Institute (ALI), a prestigious organization comprising judges, professors, and lawyers. The ALI's aim is to distill the "black letter law" from cases to indicate trends in common law, and occasionally to recommend what a rule of law should be. In essence, they restate existing common law into a series of principles or rules.

Restatements cover broad topics, such as Contracts or Property. They are organized into chapters, titles, and sections. Sections contain a concisely stated rule of law, comments to clarify the rule, hypothetical examples, explanation of purpose, as well as exceptions to the rule.

Restatements are not primary law. Due to the prestige of the ALI and its painstaking drafting process, however, they are considered persuasive authority by many courts. The most heavily cited Restatements are the Restatement of Torts and the Restatement of Contracts.

The ALI web site contains information regarding Restatement projects, ALI membership, history and institutional processes.

Finding Cases Discussing Restatements

Annotations of cases citing a Restatement section can be found in the Appendix volumes the Restatements in print. There may be one or many Appendix volumes. They are organized by Restatement series, (i.e. citations to the first Restatement, then second, etc.), then by section number. Appendices are not cumulative. The spines indicate sections and years covered. They are updated with pocket parts, cumulative annual supplements, and semiannual pamphlets called Interim Case Citations. The same case annotations are available when using the Restatements on LexisNexis or Westlaw.

You can Shepardize a Restatement section on LexisNexis using the following formats. Note that Bluebook citation format for Restatements, or permutations thereof, will not work.

• torts second sec. 46
• property second (donative transfers) sec 25.9
• conflict of laws second sec. 6
• contracts second sec. 35 cmt. d illus. 7

You can also KeyCite a Restatement section on Westlaw using the following formats. Note that KeyCite finds significantly more citing material than Shepard's for Restatements. (See the KeyCite Publications List for additional help with citation format.)

• rest agen s 1
• rest 2d contr s 3
• rest 2d prop-lt s 1.1
• rest 3d trusts-pir s 170

Current Restatements

Listed below are print editions of the Restatements and their locations in the library. Restatements are also available on both Lexis and Westlaw:

Restatements on LexisNexis Rules (along with comments, illustrations, and notes) are searchable in separate sources from case citations. This makes searching for relevant rules very efficient on LexisNexis. Case citations are linked from individual rules. Browse tables of contents or search by keyword. Restatement drafts are in separate sources from final versions of Restatements. The first series of Restatements is not available on LexisNexis.

Retreiving Restatement sections using Get a Document is not intuitive. Search for restatement in the Get a Document Citation Formats list to determine the proper format.

Restatements on Westlaw All series of Restatements are available on Westlaw. Browse tables of contents or search by keyword. Searching the Restatements on Westlaw can be problematic, because multiple series as well as selected drafts are combined into one database along with case citations to all of them, e.g. Torts first, second, and the topic-specialized Torts third series along with citations to all series are in one database. This can make keyword searching inefficient unless you use a fielded search or use the Table of Contents mode to search within a particular Restatement. Examine your search results carefully to ensure you are looking at the current version of a rule. If a rule has been superceded, there will be note above the rule text indicating this.

Retrieving Restatement sections using Find is somewhat intuitive. The format mimics the database ID. See the listed format for KeyCite below; they will also work for Find. For a complete list of Restatement retrieval formats, search the Find Publications List for restatement.

The Drafting Process

For a short overview of the drafting process for a Restatement, see How the ALI Works .

Parties Involved

• ALI Officers: a group of approximately ten, including the Chair of the Council, President, Vice Presidents, Treasurer, Director, and Deputy Directors
• ALI Council: an elected, standing group of approximately sixty judges, professors, and lawyers
• Reporter: Head of the Restatement project appointed by the ALI Officers and Council, responsible for drafting the language of the Restatement
• Advisers: Group of professors and lawyers (usually 12-30 for a Restatement) with subject expertise appointed to advise the Reporter
• Members Consultative Group: Groups of ALI members (usually 50-75 for a Restatement) interested in the topic of a Restatement who wish to offer input
• ALI Membership: a approximately 3000 ALI members who discuss and ocasionally vote on Restatement language at annual meetings; membership gives input only near the end stages of the drafting process

Drafting Process

The following process typically takes between 9 and 21 years:

• A Reporter is appointed by the Council
• The Reporter divides the project into parts that go through the following process separately:
• The Reporter writes a preliminary draft
• The Preliminary draft is sent to the Advisers and the Members Consultative Group
• The Advisers and Members Consultative Group recommend revisions
• The Reporter, at his/her discretion, makes the revisions
• The draft goes back and forth between the Advisers and the Reporter and a series of revised preliminary drafts are made
• The Reporter and Advisers send a council draft to the Council of the Institute
• The Council suggests revisions
• The Reporter is somewhat obliged to make the suggested revisions
• The draft goes back and forth between the Advisors and the Council and a series of council drafts are made
• The Council presents a tentative draft to the ALI membership
• The draft goes back and forth between the Council and the Membership and a series of tentative drafts are made
• Issues surrounding the draft settle and a proposed final draft is usually created
• The proposed final draft (or last tentative draft) is submitted to the ALI Membership at the annual meeting
• The Membership and the Council approve the proposed final draft
• The Restatement is adopted and promulgated and the official text of the Restatement is published

Other ALI-authored works, such as Uniform Commercial Code articles, are created in a similar process. If you want assistance locating materials relating to non-Restatement ALI projects, please ask a research librarian .

TRACING THE HISTORY AND DEVELOPMENT OF RESTATEMENT SECTIONS

Legal researchers sometimes need to trace the historical development of a Restatement section, the impetus for its inclusion, which section of a prior Restatement it derived from, or how it came to be worded a certain way.

For many sections, Reporter's notes explain the development of a section, often explaining earlier versions and citations to cases that were used as the basis for the rule. Reporters notes can be found in the Appendix volumes of individual Restatements.

To trace how the text changed during the drafting process, you can compare various drafts: the tentative drafts, council drafts, preliminary drafts and proposed final drafts. Each draft has its own record in the library catalog. Use the Title Keywords search in  Hollis Classic --for example, search  restatement torts --to locate them. Drafts are also available in the microform set Archive Publications described below.

Some Restatement volumes contain conversion tables. These tables indicate where sections of drafts or sections from earlier series were included in the final, adopted version of a Restatement.

Although some Restatements are designated 2d or 3d, there are not always antecedents. For instance, the Restatement of the Law Governing Lawyers is a Restatement of the Law Third, but there has never been a first or second Restatement of the Law Governing Lawyers.

• The Proceedings of the Annual Meeting of the American Law Institute Available online from 1997 Available on Westlaw from 2000 For additional and older material, see: Reading Room KF 294 .A5 A3 Microform Room Drawer 812 An excellent research tool for those tracing the development of a Restatement section. The ALI has published the Proceedings annually since 1923, except for 1945-1955. The Proceedings contain reports to ALI members, Reporter presentations, transcripts of discussions of drafts, the text of proposed amendments, and include an index of sections discussed. For the years 1945-1955, the Proceedings are only available in the Archive Publications set described below.
• The ALI Reporter Available online from 1999 Reading Room KF 200 .A455 The ALI's quarterly newsletter contains the latest information about ALI projects, meetings, and members, including reports on actions taken on drafts and the full text of chapters approved for discussion at the annual meeting with revisions explained.
• Archive Publications Microfilm Room KF 294.A5 A43, Drawers 963-965 A microfiche set containing the text of of Restatements, all drafts, and ALI Proceedings from annual meetings for the years that were not officially published, 1945-55. It also contains drafts of four Restatement projects that were terminated before completion. The set is arranged by Restatement, by section, and chronologically. Coverage starts with the founding of the ALI in 1923. All drafts produced for ALI projects are added to this set a few years after the project is completed or terminated. There is a print guide to this microfiche collection in the Microform Room at KF 294 .A5 A43.
• American Law Institute Archives Finally, there is a well-indexed, comprehensive collection of the American Law Institute Archives at the Biddle Law Library of the University of Pennsylvania. The archive contains drafts, comments, and correspondence related to ALI projects.

Determining the Current Status of Restatement Drafts

The American Law Institute is continually working on Restatements and other projects. Researchers are often interested in determining whether a Restatement has become final, or what stage the drafting process has reached. The following tools can help answer those questions, as well as provide a history of the development of ALI projects.

Secondary research, also known as a literature review , preliminary research , historical research , background research , desk research , or library research , is research that analyzes or describes prior research. Rather than generating and analyzing new data, secondary research analyzes existing research results to establish the boundaries of knowledge on a topic, to identify trends or new practices, to test mathematical models or train machine learning systems, or to verify facts and figures. Secondary research is also used to justify the need for primary research as well as to justify and support other activities. For example, secondary research may be used to support a proposal to modernize a manufacturing plant, to justify the use of newly a developed treatment for cancer, to strengthen a business proposal, or to validate points made in a speech.

Because secondary research is used for so many purposes in so many settings, all professionals will be required to perform it at some point in their careers. For managers and entrepreneurs, regardless of the industry or profession, secondary research is a regular part of worklife, although parts of the research, such as finding the supporting documents, are often delegated to juniors in the organization. For all these reasons, it is essential to learn how to conduct secondary research, even if you are unlikely to ever conduct primary research.

Secondary research is also essential if your main goal is primary research. Research funding is obtained only by using secondary research to show the need for the primary research you want to conduct. In fact, primary research depends on secondary research to prove that it is indeed new and original research and not just a rehash or replication of somebody else’s work.

Secondary Research Guide: Definition, Methods, Examples

Apr 3, 2024

8 min. read

The internet has vastly expanded our access to information, allowing us to learn almost anything about everything. But not all market research is created equal , and this secondary research guide explains why.

There are two key ways to do research. One is to test your own ideas, make your own observations, and collect your own data to derive conclusions. The other is to use secondary research — where someone else has done most of the heavy lifting for you. 

Here’s an overview of secondary research and the value it brings to data-driven businesses.

Secondary Research Definition: What Is Secondary Research?

Primary vs Secondary Market Research

What Are Secondary Research Methods?

Advantages of secondary research, disadvantages of secondary research, best practices for secondary research, how to conduct secondary research with meltwater.

Secondary research definition: The process of collecting information from existing sources and data that have already been analyzed by others.

Secondary research (aka desk research or complementary research ) provides a foundation to help you understand a topic, with the goal of building on existing knowledge. They often cover the same information as primary sources, but they add a layer of analysis and explanation to them.

Users can choose from several secondary research types and sources, including:

• Journal articles
• Research papers

With secondary sources, users can draw insights, detect trends , and validate findings to jumpstart their research efforts.

Primary vs. Secondary Market Research

We’ve touched a little on primary research , but it’s essential to understand exactly how primary and secondary research are unique.

Think of primary research as the “thing” itself, and secondary research as the analysis of the “thing,” like these primary and secondary research examples:

• An expert gives an interview (primary research) and a marketer uses that interview to write an article (secondary research).
• A company conducts a consumer satisfaction survey (primary research) and a business analyst uses the survey data to write a market trend report (secondary research).
• A marketing team launches a new advertising campaign across various platforms (primary research) and a marketing research firm, like Meltwater for market research , compiles the campaign performance data to benchmark against industry standards (secondary research).

In other words, primary sources make original contributions to a topic or issue, while secondary sources analyze, synthesize, or interpret primary sources.

Both are necessary when optimizing a business, gaining a competitive edge , improving marketing, or understanding consumer trends that may impact your business.

Secondary research methods focus on analyzing existing data rather than collecting primary data . Common examples of secondary research methods include:

• Literature review . Researchers analyze and synthesize existing literature (e.g., white papers, research papers, articles) to find knowledge gaps and build on current findings.
• Content analysis . Researchers review media sources and published content to find meaningful patterns and trends.
• AI-powered secondary research . Platforms like Meltwater for market research analyze vast amounts of complex data and use AI technologies like natural language processing and machine learning to turn data into contextual insights.

Researchers today have access to more secondary research companies and market research tools and technology than ever before, allowing them to streamline their efforts and improve their findings.

Want to see how Meltwater can complement your secondary market research efforts? Simply fill out the form at the bottom of this post, and we'll be in touch.

Conducting secondary research offers benefits in every job function and use case, from marketing to the C-suite. Here are a few advantages you can expect.

Cost and time efficiency

Using existing research saves you time and money compared to conducting primary research. Secondary data is readily available and easily accessible via libraries, free publications, or the Internet. This is particularly advantageous when you face time constraints or when a project requires a large amount of data and research.

Access to large datasets

Secondary data gives you access to larger data sets and sample sizes compared to what primary methods may produce. Larger sample sizes can improve the statistical power of the study and add more credibility to your findings.

Ability to analyze trends and patterns

Using larger sample sizes, researchers have more opportunities to find and analyze trends and patterns. The more data that supports a trend or pattern, the more trustworthy the trend becomes and the more useful for making decisions. 

Historical context

Using a combination of older and recent data allows researchers to gain historical context about patterns and trends. Learning what’s happened before can help decision-makers gain a better current understanding and improve how they approach a problem or project.

Basis for further research

Ideally, you’ll use secondary research to further other efforts . Secondary sources help to identify knowledge gaps, highlight areas for improvement, or conduct deeper investigations.

Tip: Learn how to use Meltwater as a research tool and how Meltwater uses AI.

Secondary research comes with a few drawbacks, though these aren’t necessarily deal breakers when deciding to use secondary sources.

Reliability concerns

Researchers don’t always know where the data comes from or how it’s collected, which can lead to reliability concerns. They don’t control the initial process, nor do they always know the original purpose for collecting the data, both of which can lead to skewed results.

Potential bias

The original data collectors may have a specific agenda when doing their primary research, which may lead to biased findings. Evaluating the credibility and integrity of secondary data sources can prove difficult.

Outdated information

Secondary sources may contain outdated information, especially when dealing with rapidly evolving trends or fields. Using outdated information can lead to inaccurate conclusions and widen knowledge gaps.

Limitations in customization

Relying on secondary data means being at the mercy of what’s already published. It doesn’t consider your specific use cases, which limits you as to how you can customize and use the data.

A lack of relevance

Secondary research rarely holds all the answers you need, at least from a single source. You typically need multiple secondary sources to piece together a narrative, and even then you might not find the specific information you need.

To make secondary market research your new best friend, you’ll need to think critically about its strengths and find ways to overcome its weaknesses. Let’s review some best practices to use secondary research to its fullest potential.

Identify credible sources for secondary research

To overcome the challenges of bias, accuracy, and reliability, choose secondary sources that have a demonstrated history of excellence . For example, an article published in a medical journal naturally has more credibility than a blog post on a little-known website.

Assess credibility based on peer reviews, author expertise, sampling techniques, publication reputation, and data collection methodologies. Cross-reference the data with other sources to gain a general consensus of truth.

The more credibility “factors” a source has, the more confidently you can rely on it. 

Evaluate the quality and relevance of secondary data

You can gauge the quality of the data by asking simple questions:

• How complete is the data? 
• How old is the data? 
• Is this data relevant to my needs?
• Does the data come from a known, trustworthy source?

It’s best to focus on data that aligns with your research objectives. Knowing the questions you want to answer and the outcomes you want to achieve ahead of time helps you focus only on data that offers meaningful insights.

Document your sources 

If you’re sharing secondary data with others, it’s essential to document your sources to gain others’ trust. They don’t have the benefit of being “in the trenches” with you during your research, and sharing your sources can add credibility to your findings and gain instant buy-in.

Secondary market research offers an efficient, cost-effective way to learn more about a topic or trend, providing a comprehensive understanding of the customer journey . Compared to primary research, users can gain broader insights, analyze trends and patterns, and gain a solid foundation for further exploration by using secondary sources.

Meltwater for market research speeds up the time to value in using secondary research with AI-powered insights, enhancing your understanding of the customer journey. Using natural language processing, machine learning, and trusted data science processes, Meltwater helps you find relevant data and automatically surfaces insights to help you understand its significance.

Secondary Sources in Research

Other Academics' Observations on Primary Sources

• M.A., Modern English and American Literature, University of Leicester
• B.A., English, State University of New York

In contrast to primary sources in  research  activities, secondary sources consist of information that has been gathered and often interpreted by other researchers and recorded in books, articles, and other publications. 

In her "Handbook of Research Methods , "  Natalie L. Sproull points out that secondary sources "are not necessarily worse than primary sources and can be quite valuable. A secondary source may include more information about more aspects of the event than did a primary source ."

Most often though, secondary sources act as a way to keep up with or discuss progress in a field of study, wherein a writer may use another's observations on a topic to summarize his or her own viewpoints on the matter to progress the discourse further.

The Difference Between Primary and Secondary Data

In the hierarchy of the relevance of the evidence to an argument, primary sources like original documents and first-hand accounts of events provide the strongest support to any given claim. By contrast, secondary sources provide a type of back-up to their primary counterparts.

To help explain this difference, Ruth Finnegan distinguishes primary sources as forming the "basic and original material for providing the researcher's raw evidence" in her 2006 article "Using Documents." Secondary sources, while still highly useful, are written by someone else after an event or about a document and can therefore only serve the purpose of furthering an argument if the source has credibility in the field.

Some, therefore, argue that secondary data is neither better nor worse than primary sources—it's simply different. Scot Ober discusses this concept in "Fundamentals of Contemporary Business Communication," saying "the source of the data is not as important as its quality and its relevance for your particular purpose."

Advantages and Disadvantages of Secondary Data

Secondary sources also provide advantages unique from primary sources, but Ober posits that the major ones are economic saying that "using secondary data is less costly and time-consuming than collecting primary data."

Still, secondary sources can also provide hindsight to historical events, providing the context and missing pieces of narratives by relating each event to others happening nearby at the same time. In terms of evaluations of documents and texts, secondary sources offer unique perspectives like historians have on the impact of bills such as the Magna Carta and the Bill of Rights in the U.S. Constitution.

However, Ober warns researchers that secondary sources also come with their fair share of disadvantages including quality and scarcity of sufficient secondary data, going so far as to say "never use any data before you have evaluated its appropriateness for the intended purpose."

A researcher must, therefore, vet the qualifications of the secondary source as it relates to the topic—for instance, a plumber writing an article about grammar may not be the most credible resource, whereas an English teacher would be more qualified to comment on the subject.

Secondary Research Advantages, Limitations, and Sources

Summary: secondary research should be a prerequisite to the collection of primary data, but it rarely provides all the answers you need. a thorough evaluation of the secondary data is needed to assess its relevance and accuracy..

5 minutes to read. By author Michaela Mora on January 25, 2022 Topics: Relevant Methods & Tips , Business Strategy , Market Research

Secondary research is based on data already collected for purposes other than the specific problem you have. Secondary research is usually part of exploratory market research designs.

The connection between the specific purpose that originates the research is what differentiates secondary research from primary research. Primary research is designed to address specific problems. However, analysis of available secondary data should be a prerequisite to the collection of primary data.

Advantages of Secondary Research

Secondary data can be faster and cheaper to obtain, depending on the sources you use.

Secondary research can help to:

• Answer certain research questions and test some hypotheses.
• Formulate an appropriate research design (e.g., identify key variables).
• Interpret data from primary research as it can provide some insights into general trends in an industry or product category.
• Understand the competitive landscape.

Limitations of Secondary Research

The usefulness of secondary research tends to be limited often for two main reasons:

Lack of relevance

Secondary research rarely provides all the answers you need. The objectives and methodology used to collect the secondary data may not be appropriate for the problem at hand.

Given that it was designed to find answers to a different problem than yours, you will likely find gaps in answers to your problem. Furthermore, the data collection methods used may not provide the data type needed to support the business decisions you have to make (e.g., qualitative research methods are not appropriate for go/no-go decisions).

Lack of Accuracy

Secondary data may be incomplete and lack accuracy depending on;

• The research design (exploratory, descriptive, causal, primary vs. repackaged secondary data, the analytical plan, etc.)
• Sampling design and sources (target audiences, recruitment methods)
• Data collection method (qualitative and quantitative techniques)
• Analysis point of view (focus and omissions)
• Reporting stages (preliminary, final, peer-reviewed)
• Rate of change in the studied topic (slowly vs. rapidly evolving phenomenon, e.g., adoption of specific technologies).
• Lack of agreement between data sources.

Criteria for Evaluating Secondary Research Data

Before taking the information at face value, you should conduct a thorough evaluation of the secondary data you find using the following criteria:

• Purpose : Understanding why the data was collected and what questions it was trying to answer will tell us how relevant and useful it is since it may or may not be appropriate for your objectives.
• Methodology used to collect the data : Important to understand sources of bias.
• Accuracy of data: Sources of errors may include research design, sampling, data collection, analysis, and reporting.
• When the data was collected : Secondary data may not be current or updated frequently enough for the purpose that you need.
• Content of the data : Understanding the key variables, units of measurement, categories used and analyzed relationships may reveal how useful and relevant it is for your purposes.
• Source reputation : In the era of purposeful misinformation on the Internet, it is important to check the expertise, credibility, reputation, and trustworthiness of the data source.

Secondary Research Data Sources

Compared to primary research, the collection of secondary data can be faster and cheaper to obtain, depending on the sources you use.

Secondary data can come from internal or external sources.

Internal sources of secondary data include ready-to-use data or data that requires further processing available in internal management support systems your company may be using (e.g., invoices, sales transactions, Google Analytics for your website, etc.).

Prior primary qualitative and quantitative research conducted by the company are also common sources of secondary data. They often generate more questions and help formulate new primary research needed.

However, if there are no internal data collection systems yet or prior research, you probably won’t have much usable secondary data at your disposal.

External sources of secondary data include:

• Published materials
• External databases
• Syndicated services.

Published Materials

Published materials can be classified as:

• General business sources: Guides, directories, indexes, and statistical data.
• Government sources: Census data and other government publications.

External Databases

In many industries across a variety of topics, there are private and public databases that can bed accessed online or by downloading data for free, a fixed fee, or a subscription.

These databases can include bibliographic, numeric, full-text, directory, and special-purpose databases. Some public institutions make data collected through various methods, including surveys, available for others to analyze.

Syndicated Services

These services are offered by companies that collect and sell pools of data that have a commercial value and meet shared needs by a number of clients, even if the data is not collected for specific purposes those clients may have.

Syndicated services can be classified based on specific units of measurements (e.g., consumers, households, organizations, etc.).

The data collection methods for these data may include:

• Surveys (Psychographic and Lifestyle, advertising evaluations, general topics)
• Household panels (Purchase and media use)
• Electronic scanner services (volume tracking data, scanner panels, scanner panels with Cable TV)
• Audits (retailers, wholesalers)
• Direct inquiries to institutions
• Clipping services tracking PR for institutions
• Corporate reports

You can spend hours doing research on Google in search of external sources, but this is likely to yield limited insights. Books, articles journals, reports, blogs posts, and videos you may find online are usually analyses and summaries of data from a particular perspective. They may be useful and give you an indication of the type of data used, but they are not the actual data. Whenever possible, you should look at the actual raw data used to draw your own conclusion on its value for your research objectives. You should check professionally gathered secondary research.

Here are some external secondary data sources often used in market research that you may find useful as starting points in your research. Some are free, while others require payment.

• Pew Research Center : Reports about the issues, attitudes, and trends shaping the world. It conducts public opinion polling, demographic research, media content analysis, and other empirical social science research.

Secondary research is the analysis, summary or synthesis of already existing published research. Instead of collecting original data, as in primary research , secondary research involves data or the results of data analyses already collected.

It is generally published in books, handbooks, textbooks, articles, encyclopedias, websites, magazines, literature reviews and meta-analyses. These are usually referred to as secondary sources .

Secondary research is a good place to start when wanting to acquire a broad view of a research area. It is usually easier to understand and may not require advanced training in research design and statistics.

Secondary Research Examples

1. literature review.

A literature review summarizes, reviews, and critiques the existing published literature on a topic.

Literature reviews are considered secondary research because it is a collection and analysis of the existing literature rather than generating new data for the study.

They hold value for academic studies because they enable us to take stock of the existing knowledge in a field, evaluate it, and identify flaws or gaps in the existing literature. As a result, they’re almost universally used by academics prior to conducting primary research.

Example 1: Workplace stress in nursing: a literature review

Citation: McVicar, A. (2003). Workplace stress in nursing: a literature review.  Journal of advanced nursing ,  44 (6), 633-642. Source: https://doi.org/10.1046/j.0309-2402.2003.02853.x

Summary: This study conducted a systematic analysis of literature on the causes of stress for nurses in the workplace. The study explored the literature published between 2000 and 2014. The authors found that the literature identifies several main causes of stress for nurses: professional relationships with doctors and staff, communication difficulties with patients and their families, the stress of emergency cases, overwork, lack of staff, and lack of support from the institutions. They conclude that understanding these stress factors can help improve the healthcare system and make it better for both nurses and patients.

Example 2: The impact of shiftwork on health: a literature review

Citation: Matheson, A., O’Brien, L., & Reid, J. A. (2014). The impact of shiftwork on health: a literature review.  Journal of Clinical Nursing ,  23 (23-24), 3309-3320. Source: https://doi.org/10.1111/jocn.12524

In this literature review, 118 studies were analyzed to examine the impact of shift work on nurses’ health. The findings were organized into three main themes: physical health, psychosocial health, and sleep. The majority of shift work research has primarily focused on these themes, but there is a lack of studies that explore the personal experiences of shift workers and how they navigate the effects of shift work on their daily lives. Consequently, it remains challenging to determine how individuals manage their shift work schedules. They found that, while shift work is an inevitable aspect of the nursing profession, there is limited research specifically targeting nurses and the implications for their self-care.

Example 3: Social media and entrepreneurship research: A literature review

Citation: Olanrewaju, A. S. T., Hossain, M. A., Whiteside, N., & Mercieca, P. (2020). Social media and entrepreneurship research: A literature review.  International Journal of Information Management ,  50 , 90-110. Source: https://doi.org/10.1016/j.ijinfomgt.2019.05.011

In this literature review, 118 studies were analyzed to examine the impact of shift work on nurses’ health. The findings were organized into three main themes: physical health, social health , and sleep. The majority of shift work research has primarily focused on these themes, but there is a lack of studies that explore the personal experiences of shift workers and how they navigate the effects of shift work on their daily lives. Consequently, it remains challenging to determine how individuals manage their shift work schedules. They found that, while shift work is an inevitable aspect of the nursing profession, there is limited research specifically targeting nurses and the implications for their self-care.

Example 4: Adoption of electric vehicle: A literature review and prospects for sustainability

Citation: Kumar, R. R., & Alok, K. (2020). Adoption of electric vehicle: A literature review and prospects for sustainability.  Journal of Cleaner Production ,  253 , 119911. Source: https://doi.org/10.1016/j.jclepro.2019.119911

This study is a literature review that aims to synthesize and integrate findings from existing research on electric vehicles. By reviewing 239 articles from top journals, the study identifies key factors that influence electric vehicle adoption. Themes identified included: availability of charging infrastructure and total cost of ownership. The authors propose that this analysis can provide valuable insights for future improvements in electric mobility.

Example 5: Towards an understanding of social media use in the classroom: a literature review

Citation: Van Den Beemt, A., Thurlings, M., & Willems, M. (2020). Towards an understanding of social media use in the classroom: a literature review.  Technology, Pedagogy and Education ,  29 (1), 35-55. Source: https://doi.org/10.1080/1475939X.2019.1695657

This study examines how social media can be used in education and the challenges teachers face in balancing its potential benefits with potential distractions. The review analyzes 271 research papers. They find that ambiguous results and poor study quality plague the literature. However, they identify several factors affecting the success of social media in the classroom, including: school culture, attitudes towards social media, and learning goals. The study’s value is that it organizes findings from a large corpus of existing research to help understand the topic more comprehensively.

2. Meta-Analyses

Meta-analyses are similar to literature reviews, but are at a larger scale and tend to involve the quantitative synthesis of data from multiple studies to identify trends and derive estimates of overall effect sizes.

For example, while a literature review might be a qualitative assessment of trends in the literature, a meta analysis would be a quantitative assessment, using statistical methods, of studies that meet specific inclusion criteria that can be directly compared and contrasted.

Often, meta-analysis aim to identify whether the existing data can provide an authoritative account for a hypothesis and whether it’s confirmed across the body of literature.

Example 6: Cholesterol and Alzheimer’s Disease Risk: A Meta-Meta-Analysis

Citation: Sáiz-Vazquez, O., Puente-Martínez, A., Ubillos-Landa, S., Pacheco-Bonrostro, J., & Santabárbara, J. (2020). Cholesterol and Alzheimer’s disease risk: a meta-meta-analysis.  Brain sciences ,  10 (6), 386. Source: https://doi.org/10.3390/brainsci10060386

This study examines the relationship between cholesterol and Alzheimer’s disease (AD). Researchers conducted a systematic search of meta-analyses and reviewed several databases, collecting 100 primary studies and five meta-analyses to analyze the connection between cholesterol and Alzheimer’s disease. They find that the literature compellingly demonstrates that low-density lipoprotein cholesterol (LDL-C) levels significantly influence the development of Alzheimer’s disease, but high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglycerides (TG) levels do not show significant effects. This is an example of secondary research because it compiles and analyzes data from multiple existing studies and meta-analyses rather than collecting new, original data.

Example 7: The power of feedback revisited: A meta-analysis of educational feedback research

Citation: Wisniewski, B., Zierer, K., & Hattie, J. (2020). The power of feedback revisited: A meta-analysis of educational feedback research.  Frontiers in Psychology ,  10 , 3087. Source: https://doi.org/10.3389/fpsyg.2019.03087

This meta-analysis examines 435 empirical studies research on the effects of feedback on student learning. They use a random-effects model to ascertain whether there is a clear effect size across the literature. The authors find that feedback tends to impact cognitive and motor skill outcomes but has less of an effect on motivational and behavioral outcomes. A key (albeit somewhat obvious) finding was that the manner in which the feedback is provided is a key factor in whether the feedback is effective.

Example 8: How Much Does Education Improve Intelligence? A Meta-Analysis

Citation: Ritchie, S. J., & Tucker-Drob, E. M. (2018). How much does education improve intelligence? A meta-analysis.  Psychological science ,  29 (8), 1358-1369. Source: https://doi.org/10.1177/0956797618774253

This study investigates the relationship between years of education and intelligence test scores. The researchers analyzed three types of quasiexperimental studies involving over 600,000 participants to understand if longer education increases intelligence or if more intelligent students simply complete more education. They found that an additional year of education consistently increased cognitive abilities by 1 to 5 IQ points across all broad categories of cognitive ability. The effects persisted throughout the participants’ lives, suggesting that education is an effective way to raise intelligence. This study is an example of secondary research because it compiles and analyzes data from multiple existing studies rather than gathering new, original data.

Example 9: A meta-analysis of factors related to recycling

Citation: Geiger, J. L., Steg, L., Van Der Werff, E., & Ünal, A. B. (2019). A meta-analysis of factors related to recycling.  Journal of environmental psychology ,  64 , 78-97. Source: https://doi.org/10.1016/j.jenvp.2019.05.004

This study aims to identify key factors influencing recycling behavior across different studies. The researchers conducted a random-effects meta-analysis on 91 studies focusing on individual and household recycling. They found that both individual factors (such as recycling self-identity and personal norms) and contextual factors (like having a bin at home and owning a house) impacted recycling behavior. The analysis also revealed that individual and contextual factors better predicted the intention to recycle rather than the actual recycling behavior. The study offers theoretical and practical implications and suggests that future research should examine the effects of contextual factors and the interplay between individual and contextual factors.

Example 10: Stress management interventions for police officers and recruits

Citation: Patterson, G. T., Chung, I. W., & Swan, P. W. (2014). Stress management interventions for police officers and recruits: A meta-analysis.  Journal of experimental criminology ,  10 , 487-513. Source: https://doi.org/10.1007/s11292-014-9214-7

The meta-analysis systematically reviews randomized controlled trials and quasi-experimental studies that explore the effects of stress management interventions on outcomes among police officers. It looked at 12 primary studies published between 1984 and 2008. Across the studies, there were a total of 906 participants. Interestingly, it found that the interventions were not effective. Here, we can see how secondary research is valuable sometimes for showing there is no clear trend or consensus in existing literature. The conclusions suggest a need for further research to develop and implement more effective interventions addressing specific stressors and using randomized controlled trials.

3. Textbooks

Academic textbooks tend not to present new research. Rather, they present key academic information in ways that are accessible to university students and academics.

As a result, we can consider textbooks to be secondary rather than primary research. They’re collections of information and research produced by other people, then re-packaged for a specific audience.

Textbooks tend to be written by experts in a topic. However, unlike literature reviews and meta-analyses, they are not necessarily systematic in nature and are not designed to progress current knowledge through identifying gaps, weaknesses, and strengths in the existing literature.

Example 11: Psychology for the Third Millennium: Integrating Cultural and Neuroscience Perspectives

This textbook aims to bridge the gap between two distinct domains in psychology: Qualitative and Cultural Psychology , which focuses on managing meaning and norms, and Neuropsychology and Neuroscience, which studies brain processes. The authors believe that by combining these areas, a more comprehensive general psychology can be achieved, which unites the biological and cultural aspects of human life. This textbook is considered a secondary source because it synthesizes and integrates information from various primary research studies, theories, and perspectives in the field of psychology.

Example 12: Cultural Sociology: An Introduction

Citation: Bennett, A., Back, L., Edles, L. D., Gibson, M., Inglis, D., Jacobs, R., & Woodward, I. (2012).  Cultural sociology: an introduction . New York: John Wiley & Sons.

This student textbook introduces cultural sociology and proposes that it is a valid model for sociological thinking and research. It gathers together existing knowledge within the field to prevent an overview of major sociological themes and empirical approaches utilized within cultural sociological research. It does not present new research, but rather packages existing knowledge in sociology and makes it understandable for undergraduate students.

Example 13: A Textbook of Community Nursing

Citation: Chilton, S., & Bain, H. (Eds.). (2017).  A textbook of community nursing . New York: Routledge.

This textbook presents an evidence-based introduction to professional topics in nursing. In other words, it gathers evidence from other research and presents it to students. It covers areas such as care approaches, public health, eHealth, therapeutic relationships, and mental health. Like many textbooks, it brings together its own secondary research with user-friendly elements like exercises, activities, and hypothetical case studies in each chapter.

4. White Papers

White papers are typically produced within businesses and government departments rather than academic research environments.

Generally, a white paper will focus on a specific topic of concern to the institution in order to present a state of the current situation as well as opportunities that could be pursued for change, improvement, or profit generation in the future.

Unlike a literature review, a white paper generally doesn’t follow standards of academic rigor and may be presented with a bias toward, or focus on, a company or institution’s mission and values.

Example 14: Future of Mobility White Paper

Citation: Shaheen, S., Totte, H., & Stocker, A. (2018). Future of Mobility White Paper.  UC Berkeley: Institute of Transportation Studies at UC Berkeley Source: https://doi.org/10.7922/G2WH2N5D

This white paper explores the how transportation is changing due to concerns over climate change, equity of access to transit, and rapid technological advances (such as shared mobility and automation). The authors aggregate current information and research on key trends, emerging technologies/services, impacts on California’s transportation ecosystem, and future growth projections by reviewing state agency publications, peer-reviewed articles, and forecast reports from various sources. This white paper is an example of secondary research because it synthesizes and integrates information from multiple primary research sources, expert interviews, and input from an advisory committee of local and state transportation agencies.

Example 15: White Paper Concerning Philosophy of Education and Environment

Citation: Humphreys, C., Blenkinsop, S. White Paper Concerning Philosophy of Education and Environment.  Stud Philos Educ   36 (1): 243–264. Source: https://doi.org/10.1007/s11217-017-9567-2

This white paper acknowledges the increasing significance of climate change, environmental degradation, and our relationship with nature, and the need for philosophers of education and global citizens to respond. The paper examines five key journals in the philosophy of education to identify the scope and content of current environmental discussions. By organizing and summarizing the located articles, it assesses the possibilities and limitations of these discussions within the philosophy of education community. This white paper is an example of secondary research because it synthesizes and integrates information from multiple primary research sources, specifically articles from the key journals in the field, to analyze the current state of environmental discussions.

5. Academic Essays

Students’ academic essays tend to present secondary rather than primary research. The student is expected to study current literature on a topic and use it to present a thesis statement.

Academic essays tend to require rigorous standards of analysis, critique, and evaluation, but do not require systematic investigation of a topic like you would expect in a literature review.

In an essay, a student may identify the most relevant or important data from a field of research in order to demonstrate their knowledge of a field of study. They may also, after demonstrating sufficient knowledge and understanding, present a thesis statement about the issue.

Secondary research involves data that has already been collected. The published research might be reviewed, included in a meta-analysis, or subjected to a re-analysis.

These findings might be published in a peer-reviewed journal or handbook, become the foundation of a book for public consumption, or presented in a more narrative form for a popular website or magazine.

Sources for secondary research can range from scientific journals to government databases and archived data accumulated by research institutes.

University students might engage in secondary research to become familiar with an area of research. That might help spark an intriguing hypothesis for a research project of master’s thesis.

Secondary research can yield new insights into human behavior , or confirm existing conceptualizations of psychological constructs.

Module 1: What are primary sources? In contrast, a secondary source of information is one that was created by someone who experience first-hand or participate in the events or conditions you’re researching. For the purposes of a historical research project, secondary sources are generally scholarly books and articles. Also included would be reference sources like encyclopedias. For example, the book , published in 2000, could be used as a secondary source to learn about the UI around the turn of the twentieth century. For secondary sources, often the best sources are those that have been published most recently. If you use a secondary source that was published decades ago, it is important to know what subsequent scholars have written on the topic and what criticism they have made about the earlier work or its approach to the topic.

Secondary Data Analysis Methods Secondary data analysis involves the use of pre-existing data for research purposes. Here are some common methods of secondary data analysis: Descriptive Analysis: This method involves describing the characteristics of a dataset, such as the mean, standard deviation, and range of the data. Descriptive analysis can be used to summarize data and provide an overview of trends. Inferential Analysis: This method involves making inferences and drawing conclusions about a population based on a sample of data. Inferential analysis can be used to test hypotheses and determine the statistical significance of relationships between variables. Content Analysis: This method involves analyzing textual or visual data to identify patterns and themes. Content analysis can be used to study the content of documents, media coverage, and social media posts. Time-Series Analysis : This method involves analyzing data over time to identify trends and patterns. Time-series analysis can be used to study economic trends, climate change, and other phenomena that change over time. Spatial Analysis : This method involves analyzing data in relation to geographic location. Spatial analysis can be used to study patterns of disease spread, land use patterns, and the effects of environmental factors on health outcomes. Meta-Analysis: This method involves combining data from multiple studies to draw conclusions about a particular phenomenon. Meta-analysis can be used to synthesize the results of previous research and provide a more comprehensive understanding of a particular topic. Secondary Data Gathering Guide Here are some steps to follow when gathering secondary data: Define your research question: Start by defining your research question and identifying the specific information you need to answer it. This will help you identify the type of secondary data you need and where to find it. Identify relevant sources: Identify potential sources of secondary data, including published sources, online databases, government sources, and commercial data providers. Consider the reliability and validity of each source. Evaluate the quality of the data: Evaluate the quality and reliability of the data you plan to use. Consider the data collection methods, sample size, and potential biases. Make sure the data is relevant to your research question and is suitable for the type of analysis you plan to conduct. Collect the data: Collect the relevant data from the identified sources. Use a consistent method to record and organize the data to make analysis easier. Validate the data: Validate the data to ensure that it is accurate and reliable. Check for inconsistencies, missing data, and errors. Address any issues before analyzing the data. Analyze the data: Analyze the data using appropriate statistical and analytical methods. Use descriptive and inferential statistics to summarize and draw conclusions from the data. Interpret the results: Interpret the results of your analysis and draw conclusions based on the data. Make sure your conclusions are supported by the data and are relevant to your research question. Communicate the findings : Communicate your findings clearly and concisely. Use appropriate visual aids such as graphs and charts to help explain your results. Examples of Secondary Data Here are some examples of secondary data from different fields: Healthcare : Hospital records, medical journals, clinical trial data, and disease registries are examples of secondary data sources in healthcare. These sources can provide researchers with information on patient demographics, disease prevalence, and treatment outcomes. Marketing : Market research reports, customer surveys, and sales data are examples of secondary data sources in marketing. These sources can provide marketers with information on consumer preferences, market trends, and competitor activity. Education : Student test scores, graduation rates, and enrollment statistics are examples of secondary data sources in education. These sources can provide researchers with information on student achievement, teacher effectiveness, and educational disparities. Finance : Stock market data, financial statements, and credit reports are examples of secondary data sources in finance. These sources can provide investors with information on market trends, company performance, and creditworthiness. Social Science : Government statistics, census data, and survey data are examples of secondary data sources in social science. These sources can provide researchers with information on population demographics, social trends, and political attitudes. Environmental Science : Climate data, remote sensing data, and ecological monitoring data are examples of secondary data sources in environmental science. These sources can provide researchers with information on weather patterns, land use, and biodiversity. Purpose of Secondary Data The purpose of secondary data is to provide researchers with information that has already been collected by others for other purposes. Secondary data can be used to support research questions, test hypotheses, and answer research objectives. Some of the key purposes of secondary data are: To gain a better understanding of the research topic : Secondary data can be used to provide context and background information on a research topic. This can help researchers understand the historical and social context of their research and gain insights into relevant variables and relationships. To save time and resources: Collecting new primary data can be time-consuming and expensive. Using existing secondary data sources can save researchers time and resources by providing access to pre-existing data that has already been collected and organized. To provide comparative data : Secondary data can be used to compare and contrast findings across different studies or datasets. This can help researchers identify trends, patterns, and relationships that may not have been apparent from individual studies. To support triangulation: Triangulation is the process of using multiple sources of data to confirm or refute research findings. Secondary data can be used to support triangulation by providing additional sources of data to support or refute primary research findings. To supplement primary data : Secondary data can be used to supplement primary data by providing additional information or insights that were not captured by the primary research. This can help researchers gain a more complete understanding of the research topic and draw more robust conclusions. When to use Secondary Data Secondary data can be useful in a variety of research contexts, and there are several situations in which it may be appropriate to use secondary data. Some common situations in which secondary data may be used include: When primary data collection is not feasible : Collecting primary data can be time-consuming and expensive, and in some cases, it may not be feasible to collect primary data. In these situations, secondary data can provide valuable insights and information. When exploring a new research area : Secondary data can be a useful starting point for researchers who are exploring a new research area. Secondary data can provide context and background information on a research topic, and can help researchers identify key variables and relationships to explore further. When comparing and contrasting research findings: Secondary data can be used to compare and contrast findings across different studies or datasets. This can help researchers identify trends, patterns, and relationships that may not have been apparent from individual studies. When triangulating research findings: Triangulation is the process of using multiple sources of data to confirm or refute research findings. Secondary data can be used to support triangulation by providing additional sources of data to support or refute primary research findings. When validating research findings : Secondary data can be used to validate primary research findings by providing additional sources of data that support or refute the primary findings. Characteristics of Secondary Data Secondary data have several characteristics that distinguish them from primary data. Here are some of the key characteristics of secondary data: Non-reactive: Secondary data are non-reactive, meaning that they are not collected for the specific purpose of the research study. This means that the researcher has no control over the data collection process, and cannot influence how the data were collected. Time-saving: Secondary data are pre-existing, meaning that they have already been collected and organized by someone else. This can save the researcher time and resources, as they do not need to collect the data themselves. Wide-ranging : Secondary data sources can provide a wide range of information on a variety of topics. This can be useful for researchers who are exploring a new research area or seeking to compare and contrast research findings. Less expensive: Secondary data are generally less expensive than primary data, as they do not require the researcher to incur the costs associated with data collection. Potential for bias : Secondary data may be subject to biases that were present in the original data collection process. For example, data may have been collected using a biased sampling method or the data may be incomplete or inaccurate. Lack of control: The researcher has no control over the data collection process and cannot ensure that the data were collected using appropriate methods or measures. Requires careful evaluation : Secondary data sources must be evaluated carefully to ensure that they are appropriate for the research question and analysis. This includes assessing the quality, reliability, and validity of the data sources. Advantages of Secondary Data There are several advantages to using secondary data in research, including: Time-saving : Collecting primary data can be time-consuming and expensive. Secondary data can be accessed quickly and easily, which can save researchers time and resources. Cost-effective: Secondary data are generally less expensive than primary data, as they do not require the researcher to incur the costs associated with data collection. Large sample size : Secondary data sources often have larger sample sizes than primary data sources, which can increase the statistical power of the research. Access to historical data : Secondary data sources can provide access to historical data, which can be useful for researchers who are studying trends over time. No ethical concerns: Secondary data are already in existence, so there are no ethical concerns related to collecting data from human subjects. May be more objective : Secondary data may be more objective than primary data, as the data were not collected for the specific purpose of the research study. Limitations of Secondary Data While there are many advantages to using secondary data in research, there are also some limitations that should be considered. Some of the main limitations of secondary data include: Lack of control over data quality : Researchers do not have control over the data collection process, which means they cannot ensure the accuracy or completeness of the data. Limited availability: Secondary data may not be available for the specific research question or study design. Lack of information on sampling and data collection methods: Researchers may not have access to information on the sampling and data collection methods used to gather the secondary data. This can make it difficult to evaluate the quality of the data. Data may not be up-to-date: Secondary data may not be up-to-date or relevant to the current research question. Data may be incomplete or inaccurate : Secondary data may be incomplete or inaccurate due to missing or incorrect data points, data entry errors, or other factors. Biases in data collection: The data may have been collected using biased sampling or data collection methods, which can limit the validity of the data. Lack of control over variables: Researchers have limited control over the variables that were measured in the original data collection process, which can limit the ability to draw conclusions about causality.
