Gopher lets you search for resources using menus. It originated at the University of Minnesota which has (as you guessed it) a gopher for a mascot. Insted of accessing with the adress of the domain, you select any entry in a gopher menu and like the human "gofers' of the world, Gopher goes out for the material you want. Gopher is like a regular library subject catalog and it will search for the holdings of many libraries for your subject.
gopher fatty.law.cornell.edu which is the Cornell Legal Information Institute of Cornell Law School.

other domain adresses are as follows:
