Evaluating information

How do you know if the information you have found is relevant or trustworthy?

It’s easy to find lots of information when you’re searching, but this doesn’t mean that it is reliable and credible information, or useful for academic research.

Web information

Review the following slides to learn about ‘fake news’, information you might find on the Internet, and some quick and easy ways to ensure that what you find is accurate, relevant, and reliable:

What about evaluation of print resources…

Most of the print resources you use will be from the library, which makes the job easier for researchers.  Libraries spend time and money selecting resources from reputable publishers and scholarly sources, so authoritative content is as convenient to find and use as information openly available on the Web.

Finding information about authors, publishers and journals

Understanding who is responsible for the content of print resources can be very helpful in deciding whether the information is likely to be from a reputable author or publisher.


AUTHOR information is usually on the back of a book, on the jacket cover, or near the contents page. The Foreword of a book often includes reference to the status or accomplishments of the authors. The journal cover, or start of a journal article usually contains author information.

The USC Library has research databases which you can search for the publications by an author, to see if they are well published and cited (Scopus & Web of Science). This example is from Scopus:
