Evaluating Web Sites
It Looks Lovely,
But Is It True?

The Internet:
It’s a big world out there.
Since you were a child, adults were selecting books for
you. Your parents chose
books for you to read, while your
teachers chose texts
for you to use.
Now that you are old enough to visit the internet, you have to
be able to make informed choices on your own.

The Big Lie
There is one belief we must unlearn as we enter
cyberspace. It is erroneous and will cause us to make
poor judgments. The mistaken belief is that . . .
All that we see in print is true.

The Internet
After all, anyone can post messages. Anyone
can create a website. Anyone can pretend to
be someone else. Anyone can try to mislead
you.
As the internet becomes a more common
mode of sharing information, and
as the number of sites grows exponentially,
you will need to distinguish fact from fiction.

Authority
Authority merely means that an author of a web
site has credentials that prove he or she is
knowledgeable in a field. After all, you don’t want
information about your health provided by an
electrician in Ohio who enjoys reading health
guides during his lunch breaks!
Thus, when you arrive at a site, you should ask
several important questions that will help you
assess the credibility of the site.

A Question of Authority
?
• Is the author’s name present?
• What type of extension is at the
end of the URL?
• Is there an “About this site” & is
an e-mail address provided?
• Is there any biographical
information listed?
• Does the author have a degree
or job experience in the field
he/she is discussing?
• Is there a tilde (~) in the address
or URL?
• Is the author affiliated with a
prominent institution?
• Does he/she include a
bibliography of his/her previous
published works?
Anonymity should be considered
suspicious. A .com extension indicates
a commercial site, whereas an edu, gov
or org extension indicates an education,
government or organization site. An
author should be forthcoming with
information about himself, his
experience, and his affiliations. If any of
the information provided seems
fraudulent, try to cross-reference his
name and check his affiliations. Also, if
a tilde appears in his URL, it indicates
that the site is a personal page created
by an individual, not an institution. In
addition, make sure the site is not
created to sell a product. Usually, a
“commercial” site will contain “com” in its
URL. Finally, use good judgment and
trust your instincts!

A Question of Accuracy
?
• Does the site contain numerous
spelling errors or numerical
inaccuracies?
• Does it include information that is
contradicted by other sites?
• Does it contradict itself?
• Is the information outdated or
obsolete?
• Are the links functioning? Are they
annotated?
• Has the site been operating
properly each time you visited?
• Is the content meaningful?
• Does it seem like fact or fiction?
You should be leery if a site includes
errors. This suggests that the author is
a questionable source of information.
So too, whenever you find a site that
seems like an ambiguous blend of fact
and fiction, or includes nonsensical
information, quickly move to another
site. Also, if a site or its links do not
operate properly, you cannot depend on
them to provide current data. In fact, you
can go to “File” and “Properties” or “Get
Info” to find the last date a site was
updated! Finally, any website that
seems intentionally confusing or
distracting should be avoided.
