Types of sources

Confused about types of sources?

This video uses humor and exaggeration to teach the difference between popular, substantive, and scholarly sources.

Primary & Secondary Information

For research projects you will be using two basic types of information: Primary and Secondary. Your instructor will usually tell you what types of information he or she expects you to use for your research. What's the difference between these types?

For an accessible text version of this infographic, click on the document linked below.

Primary (Think of this as Firsthand):

Primary sources are original materials that were created firsthand; they have not been run through the filter of interpretation.

Because primary sources are the documents or artifacts closest to the topic of investigation, they are a great way to gain insight into and an understanding of an event or topic. Often they are created during the time period that is being studied but they can also be produced later by eyewitnesses or participants.

You may find primary sources in their original format (usually in an archive) or reproduced in a variety of ways: books, microfilm, digital, etc.

Examples are:

  • Original Research (reported in journals & dissertations)
  • Diaries
  • Interviews (legal proceedings, personal, telephone, email)
  • Letters
  • Original Documents (i.e. birth certificate or a trial transcript)
  • Patents
  • Photographs
  • Proceedings of Meetings, Conferences and Symposia
  • Survey Research (such as market surveys and public opinion polls)
  • Works of Literature
  • Laws (constitutions, statutes, regulations, and court cases)

Secondary (Think of this as Second-Hand):

Secondary information is made up of accounts written after the fact with the benefit of hindsight. Therefore, secondary information interprets and evaluates primary information. Examples are:

  • Analysis & Interpretations of Original Research (reported in magazines)
  • Biographies
  • Books
  • Commentaries
  • Dissertations
  • Indexes, Abstracts, Bibliographies (used to locate primary & secondary sources)
  • Journal Articles


You'll use the OneSearch (Library Catalog), library databases, and the Web to find secondary sources.

Scholarly, Substantive, and Popular Sources

Types of Information Scholarly, Substantive, and Popular Sources Scholarly Sources (example: journals like the New England Journal of Medicine) Produced by discipline experts and aimed at other experts Communicates specialized and discipline-specific information Often reporting original research and experimentation Some scholarly content is peer-reviewed Scholarly information is a great choice for college students, though it can be challenging to read and understand for the non-expert. Substantive Sources (example: newspapers of record like the New York Times) Produced by experts or journalists and geared toward an educated -- but not necessarily expert -- audience Communicates timely, credible information of general interest Fact-checked before publication Substantive information is a great choice for community college students because it is both credible and accessible Popular Sources (example: fun magazines like Men’s Health) Produced by journalists, staff and freelance writers, even AI; aimed at the general public Provides a broad overview of topics a general readership will find entertaining Great for identifying potential topic ideas and providing general introductions to topics If you want (or need) to use popular material for academic work, talk to your professor as you'll need to be sure to supplement it with articles from scholarly and substantive sources
