I found this page over on the UC Berkeley Library site describing a set of steps to use in evaulating web pages - how to determine whether the information on the page should be trusted. The guide offers a list of suggested questions to ask, and the implications associated with the answer to those questions.

This can help you develop a critical eye when visiting a web page.

This can be helpful when you visit a web site. Topics include:

• What can the URL tell you?
• Scanning the perimeter to look for hints
• Indicators of quality information
• What do others say?
• Does it all add up?

Well worth a read, if you ever find yourself looking at a web page and wondering "is this for real?"
