Veronica is a software search tool that keeps track of Gopher menus and sites around the world. Jughead does the same thing for a specific group of Gopher menus. The result of a Veronica or Jughead search is a custom menu, containing whatever items where found. Selecting any item from this menu automatically connects you to the appropriate Gopher, where it may happen to be. In fact, unless you specifically ask, you will not even know what computer you are using or what country it is in.
Servers provide another method of finding information that is spread around the Internet.
WAIS is able to access any of a large number of data bases. To start, you tell WAIS which databases you wish to search. Next, you specify a list of one or more keywords to search for.
