The Z39.50 Maintenance Agency Page, includes documentation and information related to the development and ongoing maintenance of the Z39.50 standard.

A Z39.50 Resource Page, prepared by Robert Waldstein (AT&T), will provide hyperlinks to many Z39.50-related resources.

Using a Z39.50 client, it is currently possible to search the Library of Congress Books File and Name Authority File. Information that will be required to configure your Z39.50 client to search the LC server directly is provided in LC Z39.50 Server Configuration Guidelines. It is also possible to access the LC server by using the appropriate search forms listed below.

Searching Through LC's WWW/Z39.50 Gateway

Listed below are databases that can be searched using this gateway. The gateway makes use of the ZClient public domain software that is available from CNIDR. It should be noted that many search and retrieval capabilities that are available in the Z39.50 protocol are not implemented in this gateway. The Initialization, Search, and Retrieval facilities have been implemented. However, the TCP/IP connection will close after the search or retrieval response has been received. Follow-on searches or additional record requests are not possible at this time, however, one can direct another search request to the same target making necessary alterations to the search term or to the value of the number of records to be retrieved.

Where applicable, the software vendor for the target Z39.50 implementation is given in parentheses after the name of the institution.
