ANSI Z39.50
Z39.50

    Information Retrieval Service
   Definition and Protocol Specification for Library
   Applications, officially known as ANSI/NISO Z39.50-1992, and
   ANSI/NISO Z39.50-1995.  This standard, used by WAIS,
   specifies an OSI application layer service to allow an
   application on one computer to query a database on another.

   Z39.50 is used in libraries and for searching some databases
   on the Internet.  The US <Library of Congress> is the official
   maintanence agency for Z39.50.

   Index Data, a Danish company, have released a lot of Z39.50
   code.  Their website explains the relevant ISO standards
   and how they are amicably converging in Z39.50 version 4.0.
