How to evaluate it

Look for author's name, title, affiliation, and contact information.

Read the "about" section of the site.

Look for trusted web sites such as:

Academic institutions (e.g. McGill University)
Government (e.g. U.S. Department of Education)
Professional associations (e.g. American Psychological Association)
Research centers (e.g. National Institutes of Health)
Print publishers (e.g. Sage)
Cultural institutions (e.g. British Museum)

Look for domains:

.edu usually has academic content, but watch out for students' personal pages.
.gov is a good source of statistical, health, scientific, and other information.
.com means the site is commercially sponsored, and the information is suspect. Must meet other criteria to be used for coursework.
.org could be a cultural institution, church, political party, or interest group. Apply all evaluative criteria.

Look for positive reviews, awards, or citations for the site.

Follow web guides selected by librarians or other experts.
