When you do research, you will use books, newspapers, magazines, academic journals, and Internet resources. Most of the print resources are reviewed and edited by experts in their fields, so you can usually use them as support for your research without worrying that the information may be incorrect. On the other hand, a lot of the information on the Internet has not been reviewed or edited by experts even though it may look very convincing. Many beautiful websites are created by elementary school students, for example.
