Check these aspects of a Web site before using it as a source:
Currency:
Was it published recently?
Relevancy:
Does it answer part of your research question?
Authority: Can you trust the author's
opinion based on their credentials?
Accuracy: Can the claims be confirmed
or supported by other research?
Purpose: Was it created in order to
research or educate?
If you can answer "no" to any of these questions, your Web site failed the CRAAP test.
