Bibliographic and holdings data from the German Union Catalogue of Serials (ZDB) – ZDB change service

The weekly deliveries of the ZDB change service contain all the newly recorded and altered bibliographic and holdings data of the ZDB from the time of the last delivery:

Alternative: Access to metadata via SFTP client.

Each delivery will be deleted after 100 days.

For institutions actively taking part in ZDB, an individual selection and provision of weekly changes containing solely one’s own insitution’s holdings data in MARC 21 format (also in XML structure) is available for a fee.
In addition, by participating in the joint data services of the EZB and ZDB (website in German language only) one’s own insitution’s holdings data as well as licensing information regarding the periodical publications in both systems can be obtained comfortably through the ZDB change service.
