Evaluating Sources

Choosing the best sources for a particular assignment or paper

Use the following criteria to help judge whether the materials you’ve collected will be suitable for your assignment/paper. It may be difficult in some cases to apply these criteria directly to every publication.

Credibility of Author(s)
- Is information given about degrees, experience in the field?
- Is the author mentioned or cited in other sources you’ve examined?

Date of publication
- The topic determines how recent your sources need to be, e.g., a topic from current events or in a rapidly changing field needs the most recent sources available. Older material may be suitable for historical or biographical topics.
- Books written within the last 5-10 years may be considered current; periodicals should be within the last 2-3 years to be considered current.
- Other criteria being equal, the more current, the better.

Relevance of publication
- Does it relate directly to your topic?
- For books; skim title, preface, table of contents, index
- For periodical articles: look at subheadings, abstracts

Intended audience
- “Popular” publications are written for the general public in easily understood language. Often they have no footnotes or bibliography. They can be useful but may oversimplify.
- “Scholarly” publications are written for an academic audience, usually by a specialist in the field. They may use technical terms and specialized vocabulary. They usually have extensive footnotes and bibliographies.
- Depending on your topic, either or both of these types of publications might be useful.

Content
- Documentation: are opinions and facts supported by reference to other authorities or footnotes?
- If a controversial topic, are conflicting points of view acknowledged?
- Are emotional words and expressions used to sway the reader?
- Is the presentation logical and sensible?
- Point of view: is the material biased by the author’s personal beliefs, and/or the general political or social climate?

Conclusion: After considering all these criteria, does the source seem appropriate for your assignment?
