This is a mix of three powerpoints that were offered on the internet. The main one I used has the copyright on every slide, Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/. I added slides from (designed, compiled by and mostly written by v guarino)-that was written on the second slide. I also added from a free powerpoint by Michele K. Haralson at Samford University. Thanks all!

Evaluating web sites

  1. 1. 1Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ Evaluating Web Sites It Looks Lovely, But Is It True?
  2. 2. 22Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ 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.
  3. 3. 33Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ 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.
  4. 4. 44Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ 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.

  8. 8. Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ AuthorityAuthority WhoWho created the Website?created the Website?  Is there an “About”, “Biography”, or “Who am I” page that tells about the author?  What qualifications does this author have to write on this topic; is the author an expert?  Is there a “Contact” page with information provided?  Where is this information being published from?
  9. 9. 99Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ 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.
  10. 10. 1010Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ 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!

  18. 18. 1818Copyright © 2007 Linda Valley All rights reserved.Copyright © 2007 Linda Valley All rights reserved. http://www.mylibraryrocks.com/http://www.mylibraryrocks.com/ 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.
