Z39.50 is a IETF defined protocol for communicating with search engines. Not all engines support this protocol...

Z39.50 is an ANSI/NISO Standard. There are some RFC's for Z39.50 though... (one example ftp://ftp.rfc-editor.org/in-notes/rfc1729.txt ).

Z39.50 is widely used for library catalogue interfaces. Michael Schlenker
