Ask Here PA Online Research Help

Ask Here PA is a 24/7 chat reference service for Pennsylvania residents. You will be connected to a librarian who can help you with many of your research questions, but remember that he or she does NOT work at Seton Hill and therefore will not have access to our databases or information about your SHU library account.

Planning Tools

Evaluating Sources

The C.R.A.P. method is a framework for beginning to evaluate sources. You need to look at the source itself AND do some fact-checking outside the source, too.


¨ Currency—consider:

§  When the source was created or last updated?

§  Is this current enough for your topic (some fields change more rapidly than others)?

¨ Reliability (the content itself)

§  Are the sources of the information documented (cited)?

§  Is the content mostly opinion or mostly verifiable information?

§  Is the source summarizing or re-stating a different source? If so, "go upstream" to that original source and use it, instead.

§  When in doubt, do a quick web search to see if anyone else has already fact-checked the claims.

¨ Authority (the author or creator)

§  Who created this resource?

§  Is the creator an expert on this topic?

§  Does the creator have any institutional affiliations?

§  "Read laterally"-- do some quick searching to find out what others say about the author. What kind of reputation do they have?

¨ Purpose (the publishing source and/or medium)

§  Why was the resource created?

§  Who is the intended audience?

§  Does the publishing source have an agenda? (E.g., are they trying to get you to support a certain candidate or buy a product?)

§  Again, "read laterally"-- do some quick searching to find out what others say about the publication. What kind of reputation does it have?

§  Are there ads? A lot of them?
