Use the criteria below to help you evaluate a source. As you do, remember:
Each criterion should be considered in the context of your topic or information need. For example, currency changes if you are working on a current event vs. a historical topic.
Weigh all four criteria when making your decision. For example, the information may appear accurate, but if the authority is suspect you may want to find a more authoritative site for your information.
When in doubt about a source, talk about it with your professor or a librarian.
