Here are the information literacy basics for second semester students taking the 199 Research Based Writing Course.

Scholarly, Trade, and Popular Sources

Scholarly Sources

Scholarly sources are often required for college level research.  They have the highest level of authority, as they are written by experts in the discipline, generally PhDs.  Many but not all of them are peer-reviewed, also known as refereed. In the peer-review process, articles are scrutinized by a panel of experts to verify accuracy, validity, and value to the profession.


  • A Scholarly Source will ALWAYS be written by an expert – a PhD. affiliated with a college or university, for example.
  • A Scholarly Source will ALWAYS include a long list of citations or references at the end of the work.

Trade Sources

Trade journal articles are written by those practicing in the field. The authors may be nurses, teachers, managers, engineers, etc. The purpose for the journal is to share information and practical strategies among people who are working in a profession. They are less lengthy and may have a few or no references at the end.

Popular Sources

Popular sources are those written by journalists or freelance writers. They are meant to appeal to the general public, often with sensationalized titles, glossy photos and illustrations, and many advertisements. Their main purpose is to entertain and generate revenue.

What do you Need?

Before you begin looking for articles, have a clear sense of the assignment and your professor's expectations.

  • What sort of sources are required or allowed?
  • How many will you need?

If you are not sure, ask your professor. A librarian can help you to locate proper sources and/or help you to review the sources you have found.

If you have free rein over the types of resources to use for a paper, think about what you need:

  • Does it need to be current and topical?
  • Does it need to be verified by scholars in the discipline?
  • Does it need to be as unbiased as possible?

Choose source types on these bases, with a critical eye.
