Evaluating Resources - a new look

From the site: . (

Start with the sites you know!

Check the URL:

  • Notes on Personal Pages:
    • Not always reliable, try to learn more about the author.
    • URL usually includes the person’s name.
    • If their name isn’t the site name, it will likely be in the URL after a tilde or percentage sign.

Type of Domain:

The domain type should match the content type:

.com = commercial

.edu = educational

.mil = military

.gov = government

.org = nonprofit

Who Published It?

  • Find the agency or person that published the article
  • Reliable publisher = reliable content and authors
  • Look at the first part of the URL between http:// and the first /.

Who Wrote It?

  • Find out who is accountable for the information.
  • Find the author/organization responsible for the content.
  • Look for a link or About Me/About Us/Background page that will tell you more about them
  • Look for info on their education and experience
  • Evaluate what you know about them and decide if you believe they are qualified to write about the topic.


  • An outdated source is not always credible.
  • Current topics: publishing dates are important
  • Outdated topics: date should be near the time the content became known.

Check Sources

  • Look at how sources are cited and what type of source is used.
  • Scholarly content should always have source info, and should not be an opinion piece.
  • Check the sources for reliability and workability.

Links to the Site

  • Links from other reliable sites shows credibility
  • If they are the only one linking to the site (from other parts of their site) then it may not be reliable.
