Evaluating Sources: It's as Easy as A-B-C


Determine the author's education or professional experience.

  • Check the header and footer of a Web page for information or a link to information about the author or sponsor.
  • Scan the beginning and end of the source to find a description of the author's credentials.
  • Search catalog or a database to locate books or articles by the same author.


Check out the point of view and purpose.

  • Read the "About Us" or the "About this Site" in web sources. Does the website or page have a extremely slanted point of view?
  • Look for footnotes or references that document the information in the source.
  • Skim the text of a source to decide if the author is attempting to sell a product or make a false claim.
  • Look for descriptions or reviews that acknowledge the pros and cons of a product, service, or opinion.


Evaluate the currency of the information.

  • When was the source was written or updated. Is it still accurate or relevant?
