Library of Congress Z39.50 Gateway

In July 2023, the Library of Congress will decommission this Z39.50 Gateway for access to the LC Catalog and the Handbook of Latin American Studies. Please direct your web searches to the LC Catalog (https://catalog.loc.gov) or to HLAS Web (https://hlasopac.loc.gov). The Library recommends that machine-to-machine queries use Z39.50/SRU directly, which is more efficient. Configuration specifications for Z39.50/SRU queries are available at: https://www.loc.gov/z3950/lcserver.html.

About the Z39.50 Gateway

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 was originally approved by the National Information Standards Organization (NISO) in 1988.

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

Using a Z39.50 client, it is currently possible to search the Library of Congress bibliographic 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 under "Search Library of Congress Catalog" above.

This gateway makes use of an earlier version of the ISearch-CGI public domain software that was created by the Clearinghouse for Networked Information Discovery and Retrieval (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.
