But when you're looking for information on the Web for school -- or really any time that you care that what you find is true and up-to-date -- you have to evaluate the website to make sure that you can trust the information on it.
Here are some questions to ask when you're looking at a website that will help you decide whether or not it's good:
Authority of Web Documents - Who made it?
Accuracy of Web Documents
Currency of Web Documents - When was it last updated?
Objectivity of Web Documents - Is it clear what it's about?
Sometimes, there is no good Web site. In that case, ask a librarian for help, go to a book, encyclopedia or magazine. Sometimes it's hard to believe, but books actually contain a LOT of helpful information!
