Evaluating Your Sources

Types of sources are books, journals, and magazines - both online and hardcopy - along with websites, interviews, documentaries etc…

When selecting a source for research, general items are important for initial evaluation:

  • Publisher: Who is the publisher of the article and are they highly regarded and trustworthy on the topic?
  • Author(s) Credentials: What do you know about the author(s) and their qualifications on the topic? Are their qualifications listed?
  • Purpose and Audience: Why was the source created and who is the target audience?
  • Bias: Does the publisher or author state an opinion on the subject and does the bias affect the accuracy of the information?
  • Evidence: Does the source provide valid evidence that includes statistics, examples and/or expert testimony?

Scholarly periodicals are written by professionals in the field and may be original research or an extension of previous research with a list of references at the end. These periodicals are reviewed by peers or other experts in their field who suggest revisions by the author before final submission for publication.

Information on the Internet

The Internet provides a plethora of information, some good, and some bad. Four ways of analyzing information on the Internet are to understand the credibility of the author, the author's knowledge of the literature, the publishing body, and accuracy & verifiability of the information (Munger). Below are questions to ask yourself as you review information on the Internet.

Authorship
  • Do you recognize the author's name?
  • If not, does the site link to a reputable site?
  • Does the site contain biographical information to suggest the author is qualified on the subject?
Knowledge of Literature
  • Does the author appear knowledgeable about the major literature in the field?
  • Is there a bibliography?
  • Are there notes or links throughout the information?
  • Accuracy & verifiability of information
  • Is the site well constructed?
  • Is the information written well?
  • Are the claims supported by specific, appropriate evidence?
Accuracy and Verifiability of Information
  • Is the information timely and up to date?
  • Was the document created or updated recently?
  • Does the document rely on recent data?
