Part of being a critical and responsible user of information is evaluating what you read.
Always evaluate websites for information quality and reliability because anyone can put information on the Internet.
Academic research is different from personal research because academic research requires current, correct, and well-documented information written by institutions/people who are authorities on their subjects.
Sites should be unbiased (UNLESS biased information is useful for a particular assignment).
The World Wide Web is a place of business, and sites that want to sell products or services have a different purpose from sites that exist to educate.
