The NASA/IPAC Extragalactic Database (NED) is an ongoing project,
funded by NASA, to make data and literature on extragalactic objects
available over computer networks. NED is an object-oriented database
which contains extensive information for nearly 132,000 extragalactic
objects taken from about major catalogs of galaxies, quasars, infrared
and radio sources. NED provides positions, names, and other basic
data (e.g. magnitude types, sizes and redshifts as well as
bibliographic references and abstracts). Searches can be done by
name, around a name, and on an astronomical position. NED contains a
tutorial which guides the user through the retrieval process. Telnet
to ipac.caltech.edu and log in as ned.
