Z39.50 ➨ Z39.50 is a national and international standard defining a protocol for computer-to-computer information retrieval. It is a client–server, application layer communications protocol for searching and retrieving information from a database over a TCP/IP computer network. It is covered by ANSI/NISO standard Z39.50, and ISO standard 23950. The National Information Standards Organization of the United States (NISO) relating to libraries begin with Z39. To use Z39.50, you will need either special software or have an ILS with Z39.50 capabilities. Z39.50 acts like a “back door” into a library catalog. In order to download another library’s records, that library has to allow Z39.50 access to its catalog. If it does, though, there is no fee to pay the library providing the record.
