How do I evaluate my sources?

Not all information is equally valuable. Any information should be carefully examined to determine its usefulness and quality.

1. Evaluating Web Sites

2. Evaluating Articles and Books
  • Authority
  • -What are the author's credentials, educational background, experience, past writings? Check Marquis Who's Who Online or other biographical sources.
  • -Is the author's name cited in other sources or bibliographies? Respected authors are cited frequently by other scholars.
  • Date of Publication
  • -Is currency important to your research?
  • -If so, when was the source published?
  • Topics in the sciences and business often demand current information. Topics in the humanities may require older material.
  • Objectivity
  • -Is the information supported by facts and evidence, or is it someone's opinion?
  • Accuracy and Quality of Content
  • -Can the information be verified by other sources?
  • -How does the information compare with other sources?
  • -If it is a book, what do book reviewers have to say?
