  4. Accuracy - Has the source been reviewed? Did they cite their sources? Who did they cite?
  5. Purpose - Why was the source created? Who is the intended audience? Where was it published? In what medium?

Searching TIps

To find out more about an author: 

Google the author's name or dig deeper in the library's biographical databases.

To find scholarly sources: 

When searching library article databases, look for a checkbox to narrow your results to Scholarly, Peer Reviewed or Peer Refereed publications.

To evaluate a source's critical reception: 

Check in the library's article databases to find reviews of the source in order to get a sense of how it was received in the popular and scholarly press.

To evaluate internet sources: 

The internet is a great place to find both scholarly and popular sources, but it's especially important to ask questions about authorship and publication when you're evaluating online resources. If it's unclear who exactly created or published certain works online, look for About pages on the site for more information about the authorship, or search for exact quotations from the text in Google (using quotation marks) to see if you can find other places where the work has been published.

Use lateral reading to see what others say about your source:

While applying the CRAAP Test to a website, that site isn't always the best place to answer questions concerning authority, accuracy, and point of view about itself. You can not always trust what an author or organization says about themselves, and there are sites that may look very professional and credible that are actually promoting a certain agenda or viewpoint. 

If you are unfamiliar with a online source, it is good practice to open a new tab and perform a search on the author and/or organization providing the source. This process is called Lateral Reading. In addition to reading "down" the webpage in order to evaluate it, you open additional tabs and read "across" multiple pages to determine what others are saying about your potential source. This helps you build the body of evidence needed to determine if the source is suitable for your research need or not.
