About 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. MARC 21 is also available in an XML structure.

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. Since the bibliographic year 2009, the German National Library has been delivering its data in the format MARC 21. The point of contact for German-speaking users of the format is the Office of Library Standards at the German National Library. Most of the documents are available in German only.
