  1. Evaluating Sources Sara Memmott Social Work Librarian EMU Library smemmott@emich.edu

  2. Why Evaluate Sources? • When you use information sources in your work, they should be credible and appropriate for your needs. • The following criteria provide guidelines for systematically evaluating sources. • Different criteria will be more or less important depending on your situation or need.

  3. Criteria for Evaluating Sources • Currency • Relevance • Authority • Accuracy • Purpose The CRAAP test is adapted from the Meriam Library at California State University Chico.

  4. Currency: Timeliness of Info • When was the information published or posted? • Has the information been revised or updated? • Is the information current or out-of date for your topic? • Web sites: are the links functional? • If there is a reference list, does it include up-to-date sources?

  6. Relevance: The Importance of the Info to Your Needs • Does the information relate to your topic or answer your question? • Who is the intended audience? • Is the information at an appropriate level (i.e. not too elementary or advanced for your needs)? • Have you looked at a variety of sources before determining this is one you will use?

  7. Relevance What audience might find this web site relevant? http://www.mayoclinic.com/health/autism/DS00348/

  8. Authority: Who is the Source of the Info? • Who is the author/publisher/source/sponsor? • Are the author's credentials or organizational affiliations given? If yes, what are they? • What are the author's qualifications to write on the topic? • Is there contact information, such as an address, publisher or institution? • Web sites: does the URL reveal anything about the author or source? examples: .com .edu .gov .org .net(See http://scc.losrios.edu/~library/tutorials/c/URLs/TLDs/ for an explanation.)

  9. Authority

  10. Accuracy: How Reliable, Truthful, or Correct is this Info? • Where does the information come from? • Is the information supported by evidence? • Has the information been reviewed or refereed? • Can you verify any of the information in another source or from personal knowledge? • Does the language or tone seem biased or free of emotion? • Are there spelling, grammar, or other typographical errors?

  11. Accuracy Is information supported by evidence?

  12. Purpose: Why does the information exist? • What is the purpose of the information? to inform? teach? sell? entertain? persuade? • Do the authors/sponsors make their intentions or purpose clear? • Is the information fact? opinion? propaganda? • Does the point of view appear objective and impartial? • Are there political, ideological, cultural, religious, institutional, or personal biases?

  15. Practice Time! • Go to these two web sites about depression: • www.depression.com • www.nimh.nih.gov/health/publications/depression/complete-index.shtml • Take about 10 minutes and evaluate both sites. • Note your evaluations on the worksheet, including: • your answers to the CRAAP questions • the evidence that supports your evaluation • For this exercise, skip relevance, since this criteria only applies when you have a particular use for the resource.
