Before the Internet was made available to the general public, researchers were dependent upon libraries and personal contacts to obtain the information they needed to study a problem. Now, researchers can conduct literature reviews with search engines, and contact colleagues in other countries via E-mail over the Internet. Thus, the scope has broadened and there really is no excuse for not being able to find anything.

Because information is now so readily available, it has become essential to develop skills of discrimination to distinguish between what is good information and what isn’t. After all, virtually anyone can post something on the Web.
