  2. Internet • No quality control • Constantly changing • Use general strategies

  3. Subject Directories • Organized by subject or topic • Examples: www.about.comwww.lii.org • Yahoo! Is supported by paid advertising and if no results are found it will then automatically search in Alta Vista.

  4. Search Engines • Search the web for a certain word or phrase • Each search engine is slightly different • Try different ones… • www.dogpile.com • www.hotbot.com • www.metacrawler.com

  5. Google • Used the most • Effective • Dependable • Identifies paid sponsors’ links

  6. Google • Allows quotation marks "working mothers" • Easy to use tabs news, images.... • Advance searching and spelling fixes

  7. Google Ability restrict to specific sites & file types "windows XP" site:microsoft.com "chemical fires" filetype:ppt

  8. Searching Strategies • Become familiar with the topic • Choose search terms • Select subject directory or search engine • Use advanced searching techniques • Limit search by language, date etc… • Try and guess possible web addresses

  9. Boolean Operators • AND, OR and NOT • Should be in upper case • Use the “( )” to list the order of operations

  10. AND or “+” Retrieve sites that have both search terms Does not mean that the terms are together

  11. OR Retrieve sites that contain one or both words Used to connect synonyms

  12. NOT or “-” Retrieve the web sites that may not contain the word you specified

  13. Advanced Boolean Operators • "Near" search for words within 10-25 of each other Example: sheep NEAR/10 dip • "ADJ" searches for words that are right next to each other but in any order

  14. Advanced Boolean Operators • "FAR" searches for words that are more than 25 away from each other • "BEFORE" works like "AND", except that the terms must follow the specified order.

  15. Ranking and Relevance • Most relevant pages are listed first • Number of times the terms appear • Location of those words • How many link to that site?

  16. Evaluating Web Pages • What does the web address tell you? • Is it objective? • Look at the web address carefully ~, %, members edu, gov, org, com, ca

  17. Evaluating Web Pages • Look for author information and date. If there is no information present on the site one can e-mail the author. • When was the information last updated. Undated factual information is no better than anonymous information.

  18. Evaluating Web Pages • Look for quality information such as footnotes, links, altered information and well chosen resources • What do others say about this site? One can look up the author in Google, as well as, search the web site and find out who owns it.use alexa.com or link:URL in Google

  19. Evaluating Web Pages • Does it all add up? • Why was the web site created? • Does it make sense or is it a parody? • Is it the best resource for my project? • If you are unsure of the web site feel free to ask • your teacher or a librarian.

  20. Why Evaluate? • Cheap or free to put information on the net • Need to tell the difference between good and bad sources of information • Need to evaluate the information you find

  21. Google Books • books.google.com • Material is supplied by publishers, authors and universities • Mostly books but some articles are included • For more information: • print.google.com/googleprint/about.html

  22. Deep Web, a.k.a. “Invisible Web” • There is an invisible web you cannot see • Most of the deep web is made up of • specialized databases • Use databases and Google Scholar to find this informationscholar.google.com
