The CRAAP Test is a useful guide to evaluating resources. CRAAP is an acronym for Currency, Relevance, Authority, Accuracy, and Purpose and it represents the general categories of criteria that can be used to evaluate the information you find. Use the CRAAP Test to decide if information is appropriate for your research! See also Evaluating Information from a Citation.*

First, make sure you are looking at the most detailed version of the citation/ abstract that is available to you.
Then dig for specifics:
Sample article record from one of the library databases:
You will notice that the author is employed by an educational institution, the article was published in August 2009, it has 19 cited references, and the article is 11 pages long. In addition, even though this article was published in August 2009, it has already served as a source for another article, as designated by "Times Cited in this Database."
To ensure that the journal is peer-reviewed, you read more about it on the journal publisher’s website or even look it up in a library database (or, ask a librarian!).
