Transcript

  • 1. Is that Sitegood enough to Cite?
  • 2. There is so much information out there!
  • 3. How are you going to know if a website is good enough to use in your report?
  • 4. It’s Okay to be Confused! There are billions of websites out there Many of them are not worthy of your time and don’t belong in your bibliographies! Sometimes it’s very hard to tell treasure from trash Sometimes Web developers don’t want you to understand the difference
  • 5. Remember:Anyone can publish anything on the Web! It is your job, as aresearcher, to look for quality!
  • 6. Yeah, and how can we be sure our teacher will think it’s goodOkay, so how enough to cite?do we know ifa site is good?
  • 7. Think of CARRDSS· CREDIBILITY / AUTHORITY· ACCURACY· RELIABILITY· RELEVANCE· DATE· SOURCES BEHIND THE TEXT· SCOPE AND PURPOSE
  • 8. CREDIBILITY / AUTHORITY : Who is the author? What are his or her credentials? Education? Experience? Affiliation? Does the author’s experience really qualify him or her as an expert? Does he or she offer first-hand credibility? (For instance, a Vietnam veteran or a witness to Woodstock?) Who actually published this page? Is this a personal page or is it part of the site belonging to a major institution? (Clues pointing to a personal page: ~ tilde, %, users, members) Is the page hosted by a free server like AOL, Tripod, Geocities?
  • 9. But what if I can’t find anyauthor information?
  • 10. Look for Credibility Clues!· Words and phrases to look for: · About us, Who Am I, FAQs, For More, Company Information, Profiles, Our Staff, Home· E-mail the author · If you have no information other than an e-mail link, write a polite e-mail asking for more information.
  • 11. More Credibility Clues (What do others think?)Do a link check · In Google type link:siteaddress · Your results will show which other sites have chosen to link to this page. If respectable institutions have linked to a site, that provides a clue about the site’s credibility.Does the site appear in major subject directories like Librarian’s Index to the Internet (lii.org)?
  • 12. Truncate the URLDelete characters in the address line up to the next slash mark to see if a main page offers more information about who is responsible for publishing the page you are interested in.Go from:·http://www.statecollege.edu/history/middleages/chaucer/smith.htm·http://www.statecollege.edu/history/middleages/chaucer·http://www.statecollege.edu/history/middleages·http://www.statecollege.edu/history·http://www.statecollege.edu
  • 13. Still more Credibility CluesIf you have an author’s name but no further information about credentials, Search the name in quotation marks in a search engine or online database On the Web, include words like profile, resume, or C.V. (curriculum vitae--an academic resume) to narrow your name search You might also include the name of a college or association you can connect with the person Search the name in biographical sources on- and offline Ask your teacher-librarian for help
  • 14. ACCURACY: Can facts, statistics, or other information be verified through other sources? Based on your knowledge, does the information seem accurate? Is the information inconsistent with information you learned from other sources? Is the information second hand? Has it been altered? Do there appear to be errors on the page (spelling, grammar, facts)?
  • 15. R ELIABILITY: Does the source present a certain view or bias? Is the page affiliated with an organization that has a particular political or social agenda? Is the page selling a product? Was the information found in a paid placement or sponsored result from the search engine? Information is seldom neutral. Sometimes a bias is useful for persuasive essays or debates. Understanding bias is important.
  • 16. R ELEVANCE:Does this information directly support my hypothesis/thesis or help to answer my question?Can I eliminate or ignore it because it simply doesn’t help me?
  • 17. D ATE:When was this information created?When was it revised?Are these dates meaningful in terms of your information needs?Has the author of the page stopped maintaining it?(Be suspicious of undated material.)
  • 18. S OURCES BEHIND THE TEXT: Did the author bother to document his or her sources and use reliable, credible sources? Were those references popular, scholarly, reputable? Are those sources real? Have you or your librarian heard of or been able to verify them? Is the material reproduced (accurately) from another publication? What kind of links did the author choose? Are the hyperlinks reliable, valuable? Do the links work?
  • 19. S COPE / PURPOSE:Does this source address my hypothesis/thesis/question in a comprehensive or superficial way? Is it a scholarly or popular treatment?Is it material I can read and understand? Is it too simple? Is it too challenging?Who is the intended audience?Why was this page created? To inform or explain? To persuade? To sell?
  • 20. What can you learn from a URL?You can use the end, or suffix of a domain name to help you judge the validity of the information and the potential bias of a website.This strategy is only a guideline. People can easily purchase domains that do not reflect their actual purpose.
  • 21. URLs as clues to content .com = commercial sites  .mil = U.S. military site (vary in their credibility)  .net = networked .gov = U.S. government service provider, site Internet administrative .org = organization, site often non-profit. Some  .museum = museum have strong bias and  .name = individual agendas Internet user .edu = school or  .biz = a business university site (is it K- 12? By a student?  .pro = professional’s By a scholar?) site  ~ = personal site
  • 22. What do their URLs reveal about these sites?http://personal.statecollege.edu/~ejv114/http://www.fi.edu/wright/index.htmlhttp://www.house.gov/house/Legproc.htmlhttp://aolmembers.com/joyciev328/civalwarsong
  • 23. Practice checking foraccuracy with a few of these sites! California’s Velcro Crop Under Challengehttp://home.inreach.com/kumbach/velcro.html Facts About Serieshttp://www.idiotica.com/cranium/encyclopedia/index.htm Republic of Cascadia: Bureau of Sasquatch Affairshttp://zapatopi.net/bsa.html Dihydrogen Monoxide Research Divisionhttp://www.donotcall.gov/register/Reg.aspx For more examples: http://mciu.org/~spjvweb/evaluating.html

BOTTOM LINE: Is the web page appropriate for your purpose? Teaching Library, UC Berkeley – Spring 2008
  • 26. Remember, the free Web is not your only choice?Did you use print sources?Did you search subscription databases?Did you check with your teacher- librarian for advice?
  • 27. What about Wikipedia?What is it? Where does the information come from?When does it make sense to use it?When are other sources better choices?
  • 28. So, why should we care about all of this?
  • 29. There are bigger questions in life! You will be using information to make important decisions! Which car should I buy? Which doctor should I choose? Should my child have this surgery? Should I take this medication?· You want to be able to ensure the information you choose is reliable, credible, current, balanced, relevant, and accurate!
