This guide provides an introduction to the research process.

Evaluating Sources

You should carefully evaluate all information, whether from a book, article, or website, by asking the following questions.

You can also take SC4 Library's tutorial on evaluating sources.


  • Who?  Who is the author of this source?
    • Are they qualified to write/speak on the subject?
    • Do you detect any bias on the author’s part in relation to the subject?
  • What? What is the source?
    • Does it have a title?
    • Is it a primary source, such as an original document or creative work or is it a secondary source, such as a report or analysis of primary sources?
    • Is it authoritative or trustworthy?
  • How?
    • How was the source produced?
    • Who is the publisher or sponsoring organization?
  • Where did you find the source?
    • Was it through a library’s databases or through an internet search engine that may list results in a biased or weighted manner?
  • When was the source published? 
    • Has it been replaced or updated?
