All information from the Internet should be evaluated for accuracy and reliability. As with any resource, you must read carefully and check sources. Some things to consider:

• Check to see if the page is current. What is the date?
• Where do the facts come from? Or, is it the author's opinion?
• Is there a primary source?
• Find the name of the author and check for credentials.
