The web is a great information resource. Because there is so much information you can usually find some information on your topic, however, because anyone can put anything on the web, you need to be very careful when using the web as a research source.
You can use the following checklist to help you to determine the reliability of the information you find on a website:
Look for links providing information about the author and his or her e-mail address.
Check for "about us," "philosophy," etc. for information about the organization.
Consider if currency is especially important for the research topic.
These are collections of websites that are created and maintained by librarians to support the needs of researchers. These are helpful because they serve a quality control function by listing only credible websites.
