You can add additional terms as you survey what is available:

How To Evaluate Web Resources - CARS

Here is an easy way to remember what to look for when evaluating the information that you find. These questions will help you assess what you might find most useful.    

CARS: Credibility, Accuracy, Reasonableness, Support

Credibility the source should be authoritative, supplying some good evidence that allows you to trust it

  • Is this source trustworthy?
  • What are the author’s credentials?
  • Is he or she known or a respected authority on this topic?  
  • Is there evidence of quality control?

Accuracy - the source should be correct today (not yesterday), and gives the whole truth

  • Is the information up to date, factual, detailed, exact, comprehensive?
  • What is the intended audience and purpose?
  • Does it reflect intentions of completeness and accuracy.

Reasonableness  - the source should engage the subject thoughtfully and reasonably, concerned with the truth

  • Is the presentation fair, balanced, objective, reasoned?
  • Can you find that the author has no conflict of interest?
  • Is there an absence of fallacies or slanted tone. 

Support  - the source should provide convincing evidence for the claims made, a source you can triangulate (has at least two other sources (non web) that support it)

  • Does this information provide background sources or references?
  • Is there contact information for the author?
  • Are claims supported, documented and corroborated?

Citing Sources

There are lots of reasons to provide references to the sources that you use.

Your audience may want to know how to investigate your topic further. By providing your resources you are helping others who are interested in the same topic.

You also need to credit the people who did the research you are using otherwise you will be claiming it is your own (even if unintentionally doing so). Plagiarism is a serious offense.

Here is a definition of plagiarism:

“Plagiarism is appropriating someone else's words or ideas without acknowledgment. To understand plagiarism we must consider two questions: (1) How is plagiarism like or unlike theft— (2) Why is plagiarism considered wrong; why should we acknowledge the originator of an idea.”

(Encyclopedia of Ethics. London: Routledge, 2001. Credo Reference. 17 April 2009 <>.)

Just like in college writing, speeches should provide your audience with verbal cues to the information you have used: the SOURCE where you found your information. (This might be an interview, scholarly article, book, or website, etc.); the AUTHOR, when available, and the DATE when your source was published or accessed (for web sources and interviews).

Here are three ways to incorporate citations for your speech:

  • Use quotation marks to attribute words of another person on your note cards. You can express quotations in your speech in several ways.

  • Provide credit or citation such that the audience can trace back to the original source.

  • Paraphrasing the main ideas WITH correct attribution.  A paraphrase will replace some of the words while keeping the main idea of the original work.

For more information on how to cite sources, see the “Citation” page in this guide.
