Understanding the difference between primary vs secondary sources can be difficult, especially if you’re just starting out in academia. Researchers today have access to a huge repository of literature, ranging from articles and books to research reports, government documents, and digital records in addition to news and reviews drawn from both print and online platforms.
These different sources are classified into two groups – primary sources and secondary sources, both of which help you strengthen your research. However, it’s important to know the differences between these as journals have specific rules when citing primary vs secondary sources. This article highlights the difference between primary and secondary sources and how to tell if a source is primary or secondary.
What are primary sources?
Primary sources refer to first-hand information about a particular subject of study. It is original data and provides direct evidence regarding the topic of study. Primary sources of information are not modified in any way through analysis or interpretation but are presented in their raw form, for example data drawn from interviews and surveys, speeches, diaries, and letters. These give a direct and personal account from people who were involved in an event or development related to the research study.
Government documents, eyewitness accounts, empirical studies, original research data, historical documents, and statistical data sets, which provide original information about a topic, are some common primary source examples. Video and audio material, photographs and still images that have been clicked during an incident or experiment are also classified as examples of primary sources. Some other primary source examples include conference proceedings, newspaper, and magazines reports.
What are secondary sources?
Secondary sources of information are summaries, interpretations, evaluations, descriptions, or analyses based on primary sources. Secondary sources are authored by persons other than the original creators. Often research authors use and cite secondary sources to formulate ideas, test hypotheses, or support their own research findings.
Secondary source examples include reviews and summaries of research conducted on topics related to the study and articles that summarize and highlight key aspects of a topic. It may also include analysis and interpretation of data and information, commentaries, and opinion pieces. Reference texts such as encyclopedias and even academic textbooks that describe and review studies and information are other secondary source examples. Edited works that bring together different expert writings on a topic and biographies are also categorized as secondary sources.
Primary vs secondary sources: How to tell if a source is primary or secondary
It is important for researchers to understand the differences between primary vs secondary sources to enable them to analyze and utilize them effectively in academic writing and research work. While assessing the different types of sources of information collected during the research process, early career researchers need to consider the following points:
- Is this study authored by the same person who conducted it (primary) or is it a summary, description, analysis, or review of a study undertaken by someone who is not the original researcher? (secondary)
- Is the source providing raw or first-hand information (primary) or has the information been modified? (secondary)
- Is the researcher going to use the source for creating original research work (primary) or as a knowledge base (secondary)
Researchers must use both primary and secondary sources of information during their academic and research work. Across academic fields, primary sources are preferred as it provides original and authentic data. However, rigorous research work draws on both primary and secondary sources. It is therefore important for researchers to learn to identify and distinguish between these types of sources. Experts advise early career researchers to engage and discuss extensively with peers and supervisors to help them better understand the important aspects of the two types of sources in academic and research wiring.
Apart from knowing the difference between primary vs secondary sources, researchers are also advised to rigorously evaluate each source for quality, credibility, and recency. Most importantly, researchers must make an informed decision on the applicability of the sources and whether it aligns and contributes to the research study. Critically evaluating available literature and being able to categorize and cite primary vs secondary sources correctly can helps researchers efficiently gather and analyze information, identify possible gaps in knowledge, and strengthen the understanding of concepts.
