 Although we often focus on websites when we discuss evaluating sources, you should not assume that just because something is written in a book or in an academic journal that it must be true. All sources should be read with a critical eye.

Five Ws

1. Who

Who is the author? Are they an expert?

2. What 

What information is provided? Is this information consistent with other sources?

3. When

When was the information published?

4. Where

Where did the author find their information? Is there a bibliography or works cited list? 

5. Why

Why did the author publish this information? (To educate or inform? To persuade? To sell a product?)
