Whether you find it online, in print, or in some other form,
critical evaluation of information sources is an essential part of
research. First, be sure you know what type of information your instructor
considers appropriate for your assignment. For instance, many
instructors require the use of scholarly or scientific journal articles.
When evaluating the
credibility of information there are several key areas to consider:
Authority
Who is the author? What are his or her
credentials? Is the author associated with a reputable organization?
Who is the publisher? (Commercial publisher,
university press, professional organization?)
What is the intent of the publisher? (Sell
magazines, share research, promote a product?)
Objectivity
Does
the author state the goals of this publication? (To inform, advocate,
persuade?)
Does
the author exhibit a bias or express opinions?
Is
there any advertising presented with the information?
Does
the information appear to be valid and well-researched? Are conclusions
supported by evidence?
Are
authoritative sources cited?
Are
opposing arguments addressed?
Quality
What
type of source is it? (Book, magazine, journal, web site?)
Is it
well organized and clearly written? Are arguments presented logically?
Is the
information accurate? Are facts documented?
Are graphics
clearly presented?
Coverage
How
in-depth is the material?
Does
it offer information not found elsewhere?
Is the
material primary or secondary in nature?
Currency
How
recently was the research done and the work published?
Is
your topic one that requires current information?
