Netfind

   A research prototype that provides a simple Internet "white
   pages" user directory.  It runs on SunOS 4.0 or more recent
   systems that are connected to the Internet (however, you can
   run Netfind on one server at your site, and let the others use
   Netfind on that server).  Given the name of a person on the
   Internet and a rough description of where the person works,
   Netfind attempts to locate telephone and electronic mailbox
   information about the person.
