Internet Research: What's Credible?

From Films on Demand (captions in English)

Evaluating Websites

The quality of the information you find on the Web varies tremendously so it is always a good idea to check the information against another source. As with all information resources, whether in print or on the Internet, you evaluate its quality based on the following criteria:

  • Accuracy (Is it free from mistakes and errors?)
  • Authority (What are the qualifications of the author?)
  • Objectivity (Is there any strong bias?)
  • Currency (Is the information up to date?)
  • Coverage (To what extent is the topic explored?)

That's just the basics.  Learn more!
