Lesson 6: How to Evaluate Sources

 

          As you research your topic, you will want to evaluate the sources in terms of their worth.  Some general guidelines for evaluating sources include:

 

Authority

             Who is the author?  What are his/her credentials?  Is he/she qualified to write on the subject matter?

 

Purpose

           What is the author trying to convey to his/her audience?  Is he/she offering unbiased information or are they trying to persuade the reader to accept their opinion?  If there is bias, is the author fair and balanced in the presentation of his/her views?  Biased information does not necessarily discredit the source.

 

Content       

            Does the author write from fact or opinion?  Does he/she offer a bibliography or other evidence, such as case studies, to verify their statements?  Do these citations represent credible sources? 

 

Currency 

          Does the source offer current information?  Does the subject require up-to-date material?  (Science and technology are constantly changing, while literature and history remain timeless.)

 

 

Evaluating Internet Sources

          Since the Internet is not regulated, information accessed may or may not be credible.  Any individual can post material on a site, so the information may not always be factual.  The above criteria for evaluating general sources can be utilized for Internet sources with a few added considerations.

 

Authority 

          Try to locate the author’s name on the web page.  Attempt to verify the author’s credentials, keeping in mind that on the Internet, people can represent themselves in any way they wish.  In many cases the author will not be identified, so look for a copyright credit or organization name, which would lend credibility to the information on the website.  The domain (.com, .edu, .org, etc.) provides immediate insight as to the type of organization sponsoring a website.   

 Internet Domains

.com 

   

Commercial (companies and for-profit web sites)

www.msn.com

.org 

 

Non-profit organizations

www.pbs.org

.net 

 

Network access groups (like Internet service providers)

www.netscape.net

Note: .COM, .ORG and .NET can now be used by
anyone, regardless of the nature of the web site.

 

.gov 

 

U.S. federal government

www.firstgov.gov

.edu 

 

U.S. academic institutions granting 4-year degrees

www.bpc.edu

.mil 

 

U.S. Military

www.navy.mil

Use caution with material found on web pages sponsored by Internet service providers, such as Yahoo, MSN and Netscape.  They offer free web space for personal pages.  A tilde (~) in the URL commonly signifies a personal website.

 

Purpose

           Websites are created for a variety of purposes, including dissemination of news, advertising, entertainment and opinion.  When evaluating a website, try to ascertain the author’s purpose for creating the site.  Is the website meant to inform or persuade?  Who is the intended audience?  The reading level of the page is a good indicator of its academic worth.   

 

Content 

          Many websites will offer links or citations to support the creator’s work.  Is the author’s writing based on personal opinion or on factual information?  Good documentation suggests a more trustworthy source.  Be wary of websites that do not offer adequate support of their message.

 

Currency 

          Check for a date on the web page to affirm the currency of the given information; however, keep in mind that the date will change even if the author only corrects a minor spelling error.  As a researcher you must judge whether the material is current by comparing the information presented with that of other sources.  One indicator of an out-of-date page is the presence of broken links.

You may now proceed to the exercise for this lesson.
