Think critically about web sites and print resources.  

• Authority: Who is the author or creator?  What are their credentials for this topic?
• Content: What is the author's bias? Who was the information written for?
• Currency: What is the publication date?  When was the website last updated? Does this matter for your topic?
• Validity: Is the information accurate or valid?  Are there references to other works that support the information?
• Publisher: Do they have a good reputation?
