Bibliographic, item and holdings information is sent to Z39.50 clients when the Z39.50 server receives requests in the OPAC (OID 1.2.840.10003.5.102) or SUTRS (OID 1.2.840.10003.5.101) format.

Details of supported attributes are below. Our Z39.50 server uses attribute checking, and will only accept search requests that contain supported attributes. If it receives a search request that contains unsupported attribute(s), the Z39.50 server will send the Z39.50 client a diagnostic message.

Z39.50 searching using EndNote bibliographic software
An EndNote connection file has been created for searching our catalogue, and is available for download. This file was created by a library user, and we are unable to provide support in its use. However, any comments or corrections can be sent to the contact below and will be passed on to the file creator. The Wellcome Library does not actively promote use of EndNote or any other bibliographic software.
