The following are some general, basic criteria to consider when evaluating all your resources.
Does the information presented seem accurate? Are the facts verifiable?
Who is the author? What expertise does he or she have on this topic? Who sponsors the site? Check the domain name (.org, .edu, .gov, etc.) to determine if it is a university, business, organization, or an individual.
What is the stated purpose of the site? Check the "About..." link on a web page if there is one. What position or opinion is presented and does it seem biased? What kind of sites does this one link to?
On what date was the page created? Do you need more current information? Do links on the site still work?
Would you quote information from this site in a college research paper?
