Z39.50 Resources Page
National Information Standards Organization Z39.50 Information Retrieval Protocol (Z39.50/ISO 23950), a computer protocol that can be implemented on any platform, defines a standard way for two computers to communicate for the purpose of information retrieval. A Z39.50 implementation enables one interface to access multiple systems providing the end-user with nearly transparent access to other systems.
Mark Kelly established the original Z39.50 resource page Internet Searching with Z39.50. This resource is built upon his efforts. His work is most appreciated.
