Whenever you are considering using a website as a source, it is very important that you review the contents in detail. An easy way to make a determination is to use Jim Kapoun's Five Criteria for Evaluating Web Pages:
- Accuracy - Can you find an actual author? Is the contact information provided correct?
- Authority - Does the author have any credentials? Have they conducted any research? What makes them an expert?
- Objectivity - Is the information biased? Are they linked to other organizations (especially commercial)?
- Currency - When was the last update to this website?
- Coverage - How in depth is the material? Is it basic, informative information you can get anywhere else?
There are many other resources to evaluate web pages easily accessable through the Web.
