When we use Google, we may find a lot of quantity, but not necessarily quality.

Below is a really easy four-step process used to evaluate web sites.

C. Currency- when was the page last updated?

R. Reliability- can the information be verified with references or a bibliography? Is the information trustworthy?

A. Authority- Who created the web site?

P. Purpose- What is the purpose of the web site? Is it advertising, educational, propaganda?

Let's visit a web site and practice using the same criteria.
