Definitions
  • Internet: a global network of interconnected computers. Includes email, the www, etc.
  • WWW (World Wide Web): a service that includes a collection of documents stored on computers connected to the Internet. The contents are written in markup languages, such as html, and often contain hypertext links for moving from document to document.
world wide web www
World Wide Web (WWW)
  • Visible web: that part of the web that is searchable by search engines
  • Invisible or deep web: the non-searchable part of the web. It may be 2-500X as large as the visible web!
          • Proprietary information
          • Archival documents; older materials (pre-1980’s)
          • Library catalogs
          • Information/citations/articles from databases, etc. that cost money to access, e.g. Web of Science
          • Sites technically not accessible
ways to find information from the www
Ways to Find Information from the WWW:
  • Search engines, e.g. Google
  • Directories, e.g. Yahoo
  • Subject gateways, favorite sites/lists, such as Vet Gate
  • Specialized databases, such as PubMed, Agricola
search engines
Search Engines
  • Search engines are powerful Web search tools that enable you to trawl vast quantities of Web resources by keyword searching. Results are ranked based upon computer completed indexes of words from web pages.
  • Examples: Google, DogPile
directories
Directories
  • Large, multi-subject search tools aimed at a general audience and built by human editors.
  • Quality of resources is variable
  • Usually use very broad subject hierarchies that take a lot of browsing, with no controlled indexing.
  • Examples: Yahoo, NetVet/Electronic Zoo, DMoz
subject gateways
Subject Gateways
  • Designed to help users locate high quality Web resources in a particular subject area. Provide access to hand selected, evaluated Web resources, chosen by subject specialists and information professionals.
  • Organized by subjects for easy browsing.
  • Examples: VetGate, Free Animal Health Resources (Cornell)
search engines vs directories favorite sites gateways
Search Engines vs. Directories, Favorite Sites, Gateways
  • Use search engines for finding more specific information (visible web)
  • Use directories and subject gateways for more general information and starting points
  • Use known web sites or specialized databases when the information is likely to be found at that web site, e.g. Pub Med

Remember: No single search engine can capture all the information. More information is not always better.
