MARC 21

The MARC formats are standards for the representation and exchange of data in machine-readable form. The Network Development and MARC Standards Office (NDMSO), supported by the MARC Advisory Committee, is responsible for maintaining and developing the format.An XML version of MARC is available.

In 2004 the Committee for Library Standards resolved to deploy MARC 21 as a uniform exchange format in an effort to bring the German standards into line with international practice. The point of contact for German-speaking users of the format is the Office for Library Standards at the German National Library.

Since the bibliographic year 2009, the German National Library has been delivering its data in the format MARC 21. All preparatory work was carried out in the Changeover to MARC 21 project.

The delivery of the MAB format will end June 30th 2013.

Most of the documents are available in German only.
