Adapted from the Purdue University Writing Lab by Dr. K

The Internet can be a great tool for research, but finding quality web materials and using them to your advantage in your writing can be challenging.

OWL web site:

Why do we need to evaluate web sources?

Why do we need to evaluate web sources?

Virtually any person can publish almost anything on the Internet.

Unlike most print sources, web sources do not have to be professionally accepted and edited to be published.


Types of web pagesTypes of web pages

Informative pages Personal web pages Political/interest group

pages Marketing-oriented or

“infomercial” pages Entertainment pages


Identify the web siteIdentify the web site

Assess the authorship, content, and purpose of the web site.

This is important because many web sources are not

checked for accuracy. some personal sites are used

to express individual opinions about issues, but not necessarily the facts.



Sometimes the actual purpose of the web site may not be clearly articulated.

Can be difficult to separate advertising from accurate information.

Some marketing sites will offer misleading information in attempts to sell their products.



Whenever possible, try to locate the home page.

You can often do this by eliminating some information from the end of the URL..org .gov.com .net.edu .us.au .uk



Who is the creator of the site?

What is the purpose of the site?

Who is the audience of this site?

Can you purchase products at this site?

Is the site affiliated with a business or university?

Does the site offer idiosyncratic information about a particular person or group?


Examine for credibilityExamine for credibility

Credibility may be compromised by purposeful misinformation or by unintentional neglect.

Locating the name of the site’s creator may be challenging.

Credentials may be missing even if the author’s name is provided.



Who is the author of the site? What is the authority or expertise of

the individual or group? What else comes up when you type

the author’s name into a search engine?

Does the source have a political or business agenda?

Is the site sponsored by a political or business group? If so, what can you find out about that group?



Does the site provide a list of sources or a Works Cited page?

Can you locate any of the source material? How reliable is this material?

Are there links to other credible sites with additional information?

Does the site provide a link for emailing the author or webmaster?


Who is the author?

Is there an author or organization clearly indicated?

Can the author be contacted? What can you find out about the author? If there is no information on the site, use a

search engine. You may find the author’s homepage or other documents which mention this person.

Directory of Published Writers (http://www.writers.net).


Is there a sponsoring organization?

If there is an organization sponsoring the page, what can you learn about the organization and who they are?

(You can search the site by following links to its home page or going back to a previous level on the site.

Does the organization take responsibility for what’s on the site? Does it monitor or review what’s on the site?


Use the web address

Look at the address for the site. Does it end in .edu, indicating that it’s an educational institution? If it has .gov, it should be fairly objective government-sponsored material.

Addresses with .org are usually non-profit organizations that are advocacy groups. (The Sierra Club is an example of an advocacy group. Their postings will conform to their goals of environmental preservation. Information posted by advocacy groups may be accurate but not entirely objective.)

If the site has a .com address, it’s most likely promoting or selling something.


Accuracy of information

-Is there documentation to indicate the source of the information? There may be a link to the original source of the information.

-Can you tell how well researched the information is?

-Are criteria for including information offered? -Is there a bibliography or links to other useful

sites? Has the author considered information on those sites or considered viewpoints represented there?


Accuracy of information

-Is the information current? When was it updated? (You can check at the bottom for a "last revised" date and/or notice if there are numerous dead links on the site.)

-Is there any indication of bias on the site? -Does the site have any credentials such as

being rated by a reputable rating group? If you see a high rating, is that because of the soundness of the content or the quality of the design? ( An attractive page is not a reason for accepting its information as reliable.)


Goals of the site

-What is the purpose of the site? To provide information? Advertise? Persuade?

-Are the goals of the site clearly indicated? -Who is the intended audience? -Is there a lot of flash and color and gimmicks

to attract attention? Is that masking a lack of sound information or a blatant attempt to get you to do or buy something?


Access: How did you find the site?

Were there links from reputable sites? From ads?

If you found the site through a search engine, that means only that the site has the words in the topic you are researching prominently placed or used with great frequency. If you found the site by browsing through a subject directory, that may mean only that someone at that site registered it with that directory.


Determine depth and scope of information


Does the material show signs of research, such as references to other sources, hyperlinks, footnotes, or a reference page?

Does the author consider opposing points of view?

How closely does the site really match the information for which you are searching?

Corroborate information whenever possible!




Different from print sources: Information covered on web pages is often

presented for easy digestion and visual appeal. Information may not provide sufficient depth or

scope.Material may be affected by marketing or political

bias.

Sometimes web sources may not be the right sources for the information you need.


Assess date of informationAssess date of information

Can you locate a date on the web page?

Dates on web pages can mean: Date the author first wrote or

developed the material Date site was first available on

the Internet for public access Date site was most recently

updated, including revisions, additions, or subtractions to the material


Assess date of information

Assess date of information

Does the site clearly state a date of creation or a date for the most recent update?

More importantly, does the information cover recent changes or advances in the field or topic you are researching?
