EROMM Classic is accessible through other, machine-readable interfaces besides EROMM Search or its own user interface. These interfaces are meant to facilitate the integration of EROMM Classic into other information systems like library portals or subject gateways etc. They are, however available only for EROMM Classic, data in EROMM Web Search can currently only be searched via this website.

Z39.50 is the established, traditional network protocol for searching remote databases. Further documentation on the Z39.50 protocol can be found at the Z39.50 maintenance agency at the Library of Congres' website.

The connection details are listed below. Please note that the character encoding returned in a Z39.50 response depends on the TCP-port you connect to.

The Z39.50 server supports the output of records in a variety of formats, among them MARC 21 and UNIMARC. A list of supported BIB-1 Attributes for both database segments can be found here: http://www.gbv.de/de/services/info/z39_50/viewProfile?zTolk=2.8@gso.gbv.de.

If you are interested in records from Europe only, you may connect to the database 2.9@gso.gbv.de (with the same login details) instead.

SRU is the HTTP and XML-based “little brother” of Z39.50. Please see the SRU section on the Library of Congres' website for further details. Currently only the protocol version 1.1 is supported. In addition to Dublin Core, records can also be retrieved in MARC 21 and UNIMARC (and other formats). Please see the explain record for details on available indexes etc.

While Z39.50 and SRU are the best choice for integrating EROMM Classic in a distributed search environment, the Open Archives Initiative‘s Protocol for Metadata Harvesting facilitates frequent downloading of larger amounts of data in order to integrate them in other metadata repositories or search engines. Please see the Open Archives Intiative's website for further information. Currently the records in EROMM Classic are available in Dublin Core and MAB-2.
