  • Need a good way to evaluate a source?  Take a look at its “craap”!

    The C.R.A.A.P. method is a way to determine the validity and relevance of a source. C.R.A.A.P. stands for

    • C: Currency. When was the information published?
    • R: Relevance. How relevant to your goals is the information?
    • A: Authority. How well does the author of the information know the information?
    • A: Accuracy. How reliable is the information?
    • P: Purpose. Why does this information exist in this way?

    If the source you’re looking at is fairly current, relevant, and accurate, it’s probably a good source to use. Depending on the aim of your paper, you’ll be looking for an authority and purpose that are unbiased and informative.
