Please mail for the relevant log-in data to obtain a complete delivery in MARC 21 or MARC21-xml format, stating the required option.

Linked Data

The basic data holdings of the bibliographic records of the DNB and the ZDB plus the Integrated Authority File (GND) are available for download (available in German only) free of charge in RDFxml and RDF/turtle format under CC0 1.0 licence as part of the Linked Data Service.

Entity Facts

Entity Facts is a data service of the German National Library which provides machine-readable "fact sheets" on the "Person" entity in the Integrated Authority File (GND). The entity data are provided in JavaScript Object Notation (JSON), permitting them to be embedded simply in external applications. The data service is currently in the test phase and is therefore offered as a beta version.

Data Service updates

The data is updated via the weekly data service and through charged installments from the WWW or FTP server (MARC 21 and XML variant) or via the free OAI interface (only XML variant).
The HTML page in ISBD format (ISBD tags) is only offered for the New Release Service (ND) and the series of the Deutsche Nationalbibliografie (except for Series O) via the Data Shop and WWW and FTP servers within the Data Service (provision is charged).

Download of individual data records

Individual data records may also be obtained:

Test records

Test records (available in German only) are offered in the formats listed above. Test records in the RDFxml format can be accessed via the catalogue (available in German only).

New developments regarding data services and information on format changes

The formats are modified at defined intervals (available in German only); relevant changes are published three months in advance.
