As you decide which resources to include in your research, here are some things to think about:
Authority: Who wrote it? What sort of expertise do they have in this area?
Coverage: Is it relevant to your topic?
Objectivity: Is there any bias? If so, how much?
Accuracy: Is the information correct? Is it in alignment with other research findings or articles?
Currency: When was your resource produced? Does this matter for your topic?
So you've found a journal article that looks trustworthy--where can you find information that will help you apply the basic evaluation criteria?
