Although the Internet is a good way to get a sense of what is out there, you will need to go further before investigate using its information in your papers. Critically evaluate each website and question the following:
Authority - Is the website based on reputable and reliable sources? Is there a bibilography? Are there citations? Is the author of the website an expert on this subject?
Objectivity - Is the website free of bias? Who is responsible for the website? Are you getting an educated version of this topic, or is it just opinion?
Currency - Has the page been updated recently enough so that it reflects the most current data? Is there a date to indicate that this page is regularly evaluated and maintained?
Coverage - Does the website have valid information on the topic? Is it free of typos and errors? Does the page have a professional look and free of advertising? Are there links to other worthwhile websites?
