Tip!

When doing research, you will use a variety of sources such as books, newspaper articles, magazines or journals, and websites. To ensure you include only valid information in your research, evaluate your sources using the criteria below.

Criteria for Evaluating Sources

Determining the author for a source is important in deciding whether information is credible. The author should show some evidence of being knowledgeable, reliable and truthful.

Questions to Ask:

  • Who is the author (person, company, or organization)?
  • Does the source provide any information that leads you to believe the author is an expert on the topic?
  • Can you describe the author's background (experience, education, knowledge)?
  • Does the author provide citations? Do you think they are reputable?

It is important that the source meets the information needs and requirements of your research assignment.

Questions to Ask:

  • Does the source cover your topic comprehensively or does it cover only one aspect?
  • To what extent does the source answer your research question?
  • Is the source considered popular or scholarly?
  • Is the terminology and language used easy to understand?

The source should contain accurate and up-to-date information that can be verified by other sources.

Questions to Ask:

  • Can facts or statistics be verified through another source?
  • Based on your knowledge, does the information seem accurate? Does it match the information found in other sources?
  • Are there spelling or grammatical errors?

Some written works are ageless (e.g., classic literature) while others (e.g., technological news) become outdated quickly. It is important to determine if currency is pertinent to your research.

Questions to Ask:

  • When was the source written and published?
  • Has the information been updated recently?
  • Is currency pertinent to your research?

Every author has an opinion. Recognizing this is instrumental in determining if the information presented is objective or biased. 

Questions to Ask:

  • What is the purpose or motive for the source (educational, commercial, entertainment, promotional, etc.)?
  • Who is the intended audience?
  • Is the author pretending to be objective, but really trying to persuade, promote or sell something?
