The Z39.50 International Standard for Computer-to-Computer Information Retrieval is Promulgated

1988

In 1988 Z39.50 became the international standard defining a protocol for computer-to-computer information retrieval. "Z39.50 is a national and international (ISO 23950) standard defining a protocol for computer-to-computer information retrieval allowing a user in one system (with a Z39.50 client) to search and retrieve information from an other system (with a Z39.50 server) without knowing the search syntax of that system."

"Z39.50 is widely used in library environments, often incorporated into integrated library systems and personal bibliographic reference software. Interlibrary catalogue searches for interlibrary loan are often implemented with Z39.50 queries" (Wikipedia article on Z39.50, accessed 9-2020).
