Evaluating Sources


Evaluating the authority, usefulness, and reliability of the information you find is a crucial step in the process of library research. The questions you ask about books, periodical articles, multimedia titles, or Web pages are similar whether you're looking at a citation to the item, a physical item in hand, or an electronic version on a computer.

ALL SOURCES:

Critically Analyzing Information Sources lists some of the questions you should ask when you consider the appropriateness of a particular book, article, media resource, or Web site for your research.

BOOKS:

Use book reviews to gather critical information about books. Three ways to access them online:

ProQuest. [1986- ; use Guided search; choose book reviews from the Article Type pull-down menu; some full-text reviews]
Book Review Digest. [1983- ; excerpts from some reviews]
Bowker's Books in Print. [in-print books from any year; full-text of short reviews]

PERIODICALS:

Distinguishing Scholarly from Non-Scholarly Periodicals: A Checklist of Criteria shows how to evaluate periodicals by looking at their format, intended audience, and appearance.

WEB SITES:

Five Criteria for Evaluating Web Sites is a table of tips and questions to ask.
