When evaluating information, ask yourself

...who is the author of the information?
...what is the content? 
...why is it being presented?
...when was it created? 
Who? Who is the author/organization? expert? credentials?
What? Is the information verified, supported by evidence, college-level?
Why? Purpose of the information: to inform? sell? entertain? persuade? biased? opinion?
When? Do you need current information for your topic?  Is the information up-to-date?
Another model of evaluating sources is called the CRAAP Test.* See how the information you found holds up to the five points of this test.
