Internet sites and resources
3Outline
- PowerPoint Presentation
- Hands-on Searching
- Discussion and Questions
4Definitions
- 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.
5World 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-1980s)
- Library catalogs
- Information/citations/articles from databases,
etc. that cost money to access, e.g. Web of
Science - Sites technically not accessible
6Ways 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
7Search 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
8Directories
- 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
9Subject 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) -
10Search 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.
