    2. 2. Session overview <ul><li>Types of information on the WWW </li></ul><ul><li>Using “Search Tools” to find information </li></ul><ul><li>Evaluating WWW information </li></ul><ul><li>Citing WWW information </li></ul>
    3. 3. Types of Information on the Web <ul><li>Background Information - overviews of topics, people, places, events, organisations, companies </li></ul><ul><li>Facts and Data -government information, statistics, reports and articles </li></ul><ul><li>News & Opinion - news stories, commentaries, reviews & alternative viewpoints from newspapers and popular magazines </li></ul><ul><li>Note that in-depth information is generally best found in other resources such as scholarly journals found in library databases </li></ul>
    4. 4. Where to start? <ul><li>Avoiding the “trash” </li></ul><ul><li>It is a good idea to start with web sites that have been selected and evaluated for you. </li></ul><ul><li>Check for a Library Guide, e.g. Finding Information on Gender Issues http://www.library. qut . edu .au/ subjectpath /gender. jsp </li></ul><ul><li>There may be sites on your CLB403 OLT page </li></ul>
    5. 5. Searching the Internet: Search Tools <ul><li>As you gain confidence you may want to do your own searching </li></ul><ul><li>A good place to start is the QUT Library Internet Search Tools page http://www.library. qut . edu .au/internet/ </li></ul><ul><li>You will note that there are a vast number of them but they fall into two main types </li></ul>
    6. 6. Types of Search Tools: <ul><li>Subject Directories </li></ul><ul><li>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. </li></ul><ul><li> e.g. Yahoo! </li></ul><ul><li>INFOMINE: Scholarly Internet Resource Collections </li></ul><ul><li>. Librarian’s Index to the Internet WWW Virtual Library </li></ul><ul><li>Indexes (search engines)‏ </li></ul><ul><li>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. </li></ul><ul><li>e.g. Google </li></ul><ul><li> Metacrawler </li></ul>
    7. 7. 1. Subject Directories: Key Points <ul><li>SCOPE: Selected or “best web sites” on a topic </li></ul><ul><li>USE FOR: Searches on broad or general topics </li></ul><ul><li>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. </li></ul><ul><li>EXAMPLE: “Find best sites on women, gender etc.” </li></ul><ul><li>n.b Most Directories also have a Search facility. </li></ul>
    8. 8. A quick demonstration
    9. 9. Browsing Subject Directories: Examples <ul><li>Go to Subject Directory Librarian's Index to the Internet </li></ul><ul><li>Select People, then Women </li></ul><ul><li>Keep clicking on subjects until you come to Rights in Arab Countries </li></ul><ul><li>Scroll down. Select Resources on Women and Islam </li></ul><ul><li>Scan resources and select one of your choice. </li></ul><ul><li>Alternatively, go to WWW Virtual Library </li></ul><ul><li>Click on Social Sciences and work your way down to Women’s Studies </li></ul><ul><li>Select a relevant web site or document e.g. Women’s Edge Coalition </li></ul><ul><li>Investigate INFOMINE next </li></ul>
    10. 10. Indexes (search engines): Key points <ul><ul><li>SCOPE: Every word on billions of Web pages that are included in the Index. NOT evaluated !!! </li></ul></ul><ul><ul><li>USE FOR: Narrow or specific searches, such as those shown in the illustration. </li></ul></ul><ul><ul><li>SEARCH: Locate specific topics by entering keywords </li></ul></ul><ul><ul><li>EXAMPLE: “Find information about head scarves in French schools ” </li></ul></ul><ul><ul><li>n.b. Like Directories, Indexes now also offer browsing by category </li></ul></ul>
    11. 11. Search Tips for Indexes (search engines)‏ <ul><li>Use good keywords and alternative terms – be specific – put important words first. Use as many as you can to focus your search as necessary. </li></ul><ul><li>Combine search terms using Boolean AND, OR, NOT </li></ul><ul><li>Use the Advance search and select limiters e.g. words in title of page, domain, country or region, date, media and language </li></ul><ul><li>Here is the Google help page </li></ul>
    12. 12. A quick demonstration
    13. 13. Search engines Search Engines perform keyword searches for Web sites and documents
    14. 14. Searching Indexes :Example <ul><li>Go to search engine Google </li></ul><ul><li>Enter your keywords e.g. women in Afghanistan </li></ul><ul><li>Note the large number of results and the predominance of organisation’s sites as shown in the domain .org </li></ul><ul><li>Now try limiting or refining your search </li></ul><ul><li>Combine at least one phrase with at least one additional keyword e.g. education </li></ul><ul><li>Limit to last 3 months, domain .edu,file type .pdf, </li></ul><ul><li>Browse and select document to evaluate </li></ul>
    15. 15. Evaluating the information <ul><li>Purpose (bias?)‏ </li></ul><ul><li>Authority of the author? </li></ul><ul><li>Source of the information? </li></ul><ul><li>Currency of the information? </li></ul><ul><li>Intended audience (University level?)‏ </li></ul><ul><li>Accuracy & Completeness? </li></ul>Library © QUT Library 2003
    16. 16. Criteria <ul><li>Purpose – is it to inform or persuade? Useful for understanding different points of view.

    17. 17. Domain name as a guide to information type <ul><li>The organisation type can be particularly useful for determining the authority of a site.
