Wikipedia

An encyclopedia that can be edited by anyone. The site is a wiki meaning that anyone with access to the Internet can add to or change the information on there. Lack of any editorial control means that the quality of the information varies widely. Can be useful as a starting point, but it's a good idea to verify the information you find.
