How to Interpret The Basics |
Credibility
- Who wrote the page?
- Can you contact him or her?
- What are the credentials of the author?
- Are their authoritative links?
- Is a Works Cited included?
- Policy of Content included?
- What about this source makes it believable (or not)?
|
Credibility
- Make sure author provides e-mail or
a contact address/phone number.
- You should hold the author to the same degree of credentials, authority, and documentation that
you would expect from something published in a reputable print resource (book, journal article,
good newspaper).
- Might the page be by a hobbyist, self-proclaimed expert, or enthusiast?
- Works Cited includes reliable sources.
- Policy of Content explains inclusions and exclusions.
- Why should I believe this source over another? Why should I believe it? Why should I trust this source?
|
Accuracy
- Is the text well written? Spelling/grammar mistakes?
- What is the quality of writing?
- Is the content communicated
clearly? Do the visual effects
enhance the resource,
distract from the content, or
substitute for content?
|
Accuracy
- Compare sites. Is the information
consistent with information on
other sites?
- How many dead links are on the
page?
- Most educated people use
grammar fairly well and check their
work for spelling errors. An
occasional comma in the wrong
place is not unusual, but more than
two or three spelling or grammar
errors is cause for caution, at least.
Whether the errors come from
carelessness or ignorance, neither
puts the information or the writer in
a favorable light.
|
Reliability
- Is the information fact or
opinion?
- Does this site have
information I need to answer
my question?
- What goals/objectives does
this page meet?
- How detailed is the
information?
- What opinions (if any) are
expressed by the author?
|
Reliability
- Check “about this site.”
- Who produced this site?
- Determine if page is a mask for
advertising; if so information might
be biased.
- View any Web page as you would an infommercial on television. Ask
yourself why was this written and for whom?
|
Relevance
- Do the links complement the
documents theme?
- Is it all images or a balance of text and images?
|
Relevance
- Will this answer my question?
- Is the information useful for my
purpose?
- Are the links helpful for my purpose?
|
Date
- How old is the site?
- How often is site updated?
- How current are the links?
|
Date
- How many dead links are on the
page?
- Are the links current or updated
regularly?
- Is the information on the page
outdated?
|
Sources
- Is the information presented
cited correctly?
- Is the information verifiable?
- Works Cited included?
- Parenthical Within Text?
|
Sources
- Does the resource stand alone, or has it been abstracted from another source, perhaps losing meaning or links in the process?
2. Are the sources in the Works Cited authoritative?
|
Scope
- For what audience?
- What aspects of the subject
are covered?
- What types of resources are
provided by the links?
- Logical progression of topics
within original site (site being
evaluated)
- Information offered not easily
available in other sources
|
Scope
- Why Created?
- Is this related to the level
of audience for which the
resource has been
designed?
- Is the resource focused on
a narrow area or does it
include related topics?
- What is the level of depth
treated by this site? What is the
level of detail provided about the
subject.

CARRDSS IN A NUTSHELL
- Putting It All Together – If…
- Credibility. If the page lists the author’s credentials, and policy of content.
- Accuracy. If the page provides accurate information with limited advertising, is text well written?
- Reliability. If the writing is objective in presenting the information.
- Relevance. If the information is important to my topic? Do the links from the page work and do the links directly
relate to my topic?
- Date. Is the page current and updated regularly (as stated on the page) and are the links (if any) up-to-dated?
- Sources. If the information verifiable by including a works cited.
- Scope. If the purpose of the site can be readily determined; if the audience for whom the site is intended can be
readily determined.
