The Z39.50 Target Directory

The Z39.50 Target Directory contains all the ANSI/NISO Z39.50 (ISO 23950) and SRU/SRW targets known to us. The tables show the name, address, port, reliability info, search attributes and other data useful for achieving interoperability.

We at Index Data know that the records currently in this directory represent only a fraction of the Z39.50/SRU/SRW compliant databases that exist. Our aim is to make this directory as comprehensive as possible. To that end, we ask your help. If you are aware of a Z39.50 compliant target that is not represented in our directory, please add it or send us email with the details. Also, if you should happen to find an error in our data or have additional information, please don't hesitate to contact us so that we can make the target information as accurate and comprehensive as possible.

DISCLAIMERS: Most of the systems listed are generally made available without charge for testing or general use, but many require authorization, either for access or additional functionality. The Target Directory does not contain authentication information, and it is not meant to be a substitute for authentication/authorization procedures many targets require. In addition, the information presented here should not be considered indicative either of the functionality of the native interface of the target, or of the functionality of any given software system or installation. This directory is made available for evaluation purposes only. Although we try to make it as accurate as we can, Index Data assumes no responsibility or warranty for its correctness.
