• The contents of a library have been selected, cataloged, indexed, and organized to facilitate the retrieval of information by library users.
• Librarians are available to assist you in person, through email, or online chatting.

• Just like a library pays for subscriptions to printed journals, libraries also pay a fee for access to electronic journals.These databases contain the electronic versions of many familiar printed magazines, journals, and newspapers.
• These journals are not freely available on the Internet.
• Do you think the information you are seeking is available for free or for a fee?

• Very current, such as today's news or a press release from government, business or other organization
• Brief and not detailed
• Published by a government or association (especially statistics)
• Obscure or current subject on which it is unlikely that there has been very much information published or not likely to be found in the library.

Web site

A “home” on the World Wide Web made up “linked” computer files called web pages.

URL (uniform resource locator)

Describes the location and access method of a resource on the web. A URL is for the web what a street address is for a house. For example: http://www.tcc.edu/lrc/index.htm

Search engine

A program which acts as an index for the Internet.

Search directory

Web sites already found and organized by subjects into a convenient directory. More like a card catalog. (Yahoo)

Portal

Starting points for web activities including searching, e-mail, chats, etc. (TCC’s libraries, America Online, etc.)

• Actually searching indexes of the web
• Include web pages when registered by users (Yahoo)
• Programs called “bots” or “spiders” search for links ON pages (AltaVista)
• Programs “search” for links TO pages (Google)
