Evaluating Webpages: How You Can Find Treasures Among the Junk

Why should I take the time to evaluate information I find on the Web?

Because you can’t be sure anyone else is doing it for you! The Web is great because so many different people can contribute information. Some of the information that is found is very useful for your research papers because it is accurate, current, objective. Other information that can be found on the web is based on the person who is maintaining the webpages opinion. You must be able to recognize the difference and sift out the useful material in order to have a more accurate research paper.
