  • 1. Finding Information for CLB403 Using the WWW Irene Ryan October 2004 Library
  • 2. Session overview
    • Types of information on the WWW
    • Using “Search Tools” to find information
    • Evaluating WWW information
    • Citing WWW information
  • 3. Types of Information on the Web
    • Background Information - overviews of topics, people, places, events, organisations, companies
    • Facts and Data -government information, statistics, reports and articles
    • News & Opinion - news stories, commentaries, reviews & alternative viewpoints from newspapers and popular magazines
    • Note that in-depth information is generally best found in other resources such as scholarly journals found in library databases
  • 4. Where to start?
    • Avoiding the “trash”
    • It is a good idea to start with web sites that have been selected and evaluated for you.
    • Check for a Library Guide, e.g. Finding Information on Gender Issues http://www.library. qut . edu .au/ subjectpath /gender. jsp
    • There may be sites on your CLB403 OLT page https://olt.qut.edu.au/CLB403
  • 5. Searching the Internet: Search Tools
    • As you gain confidence you may want to do your own searching
    • A good place to start is the QUT Library Internet Search Tools page http://www.library. qut . edu .au/internet/
    • You will note that there are a vast number of them but they fall into two main types
  • 6. Types of Search Tools:
    • Subject Directories
    • Databases of web pages created and categorised by researchers. Some are evaluated by experts and some are not. Can be quite selective so you should browse/search more than one.
    • e.g. Yahoo!
    • INFOMINE: Scholarly Internet Resource Collections
    • . Librarian’s Index to the Internet WWW Virtual Library
    • Indexes (search engines)‏
    • Databases created by special software programs (called robots, spiders or crawlers) that search for and capture web pages. They then index or list all words within each page.
    • e.g. Google
    • Metacrawler
  • 7. 1. Subject Directories: Key Points
    • SCOPE: Selected or “best web sites” on a topic
    • USE FOR: Searches on broad or general topics
    • BROWSING: Browse through subject categories, usually arranged in a hierarchy, starting with the broadest or most general, and working down to specific web sites and documents.
    • EXAMPLE: “Find best sites on women, gender etc.”
    • n.b Most Directories also have a Search facility.
  • 8. A quick demonstration
  • 9. Browsing Subject Directories: Examples
    • Go to Subject Directory Librarian's Index to the Internet
    • Select People, then Women
    • Keep clicking on subjects until you come to Rights in Arab Countries
    • Scroll down. Select Resources on Women and Islam
    • Scan resources and select one of your choice.
    • Alternatively, go to WWW Virtual Library
    • Click on Social Sciences and work your way down to Women’s Studies
    • Select a relevant web site or document e.g. Women’s Edge Coalition
    • Investigate INFOMINE next
  • 10. Indexes (search engines): Key points
      • SCOPE: Every word on billions of Web pages that are included in the Index. NOT evaluated !!!
      • USE FOR: Narrow or specific searches, such as those shown in the illustration.
      • SEARCH: Locate specific topics by entering keywords
      • EXAMPLE: “Find information about head scarves in French schools ”
      • n.b. Like Directories, Indexes now also offer browsing by category
  • 11. Search Tips for Indexes (search engines)‏
    • Use good keywords and alternative terms – be specific – put important words first. Use as many as you can to focus your search as necessary.
    • Combine search terms using Boolean AND, OR, NOT
    • Use the Advance search and select limiters e.g. words in title of page, domain, country or region, date, media and language
    • Here is the Google help page http://www.google.com/help/basics.html
  • 12. A quick demonstration
  • 13. Search engines Search Engines perform keyword searches for Web sites and documents http://www.google.com.au/
  • 14. Searching Indexes :Example
    • Go to search engine Google
    • Enter your keywords e.g. women in Afghanistan
    • Note the large number of results and the predominance of organisation’s sites as shown in the domain .org
    • Now try limiting or refining your search
    • Combine at least one phrase with at least one additional keyword e.g. education
    • Limit to last 3 months, domain .edu,file type .pdf,
    • Browse and select document to evaluate
  • 15. Evaluating the information
    • Purpose (bias?)‏
    • Authority of the author?
    • Source of the information?
    • Currency of the information?
    • Intended audience (University level?)‏
    • Accuracy & Completeness?
    Library © QUT Library 2003
  • 16. Criteria
    • Purpose – is it to inform or persuade? Useful for understanding different points of view. Just be aware and look for alternative views to get a balance
    • Author – person or organisation. Do they have the qualifications to write with authority on the topic?
    • Content – Is it biased due to purpose and author’s position on the topic?
    • Currency – Check date of that information was added
    • Coverage – Is it comprehensive – do you need to check more sites?
    • Have a look net.TUTOR for activities and examples
  • 17. Domain name as a guide to information type
    • The organisation type can be particularly useful for determining the authority of a site. Government bodies will generally be within the 'gov' domain, e.g. www.qld.gov.au or www.nasa.gov . Educational bodies will often be within the 'edu' domain, e.g. www.qut.edu.au or www.ucla.edu . Commercial bodies have domain names within the 'com' domain, e.g. www.umi.com . The main organisation type domains are listed below.
    • com or co commercial
    • gov government
    • edu or ac educational or academic
    • org organisation
    • net network organisation
    • mil military
    • US domain names often do not include the country domain.
  • 18. Evaluating Internet material … ..Star Tobacco and Pharmaceuticals was founded in 1990 for the purpose of commercializing improved tobacco products. No personal author No references for “Facts” given So, who is “Star” ??
  • 19. Evaluating Internet material No clear statement of author URL shows that the document is on the The World Health Org’s server but this is not enough to confirm the authority of the information ? No reference list of sources of statistics No dates - original or revisions
  • 20. Evaluating Internet material .edu in domain Revision / update date provided Original publication date provided Contact details given
  • 21. Citing the information – web site
