It's important to evaluate any information you find, especially information you find on the Internet. Unlike books and magazines, which use editors, proofreaders, and fact checkers, there is often no one to check the quality and reliability of Internet information. Since virtually anyone can publish just about anything on the Internet, it's critical to evaluate it carefully. Here are some questions you should ask of every information source you find:
WHO?
WHAT?
WHEN?
Limit your search to a specific type of domain by typing site:edu for education or site:gov for government
Example: lymphoma site:gov
Word order matters so use the most important words first.
Example: blue sky brings back different results than sky blue
Advanced search allows Google to search a single specific web site for all the occurrences of a keyword or phrase.
