11.5 million free bibliographic data items now available from the German National Library in MARC 21 format

Press release:  1.7.2013

All the bibliographic data of the German National Library offered under "Creative Commons Zero" conditions are available free of charge as a complete package in MARC 21 format for free use. Included are more than 11.5 million bibliographic data items.

The bibliographic data up to the 2011 bibliography year are currently offered under a "Creative Commons Zero" licence (CC0). Free registration is required in order to use the data. Charges are applied to bibliographic data of the current and the previous year. The data of the next bibliography year is added to the package of free data in the first quarter of each new year.

The intention is to provide all data in all formats free of charge and under CC0 conditions for free use from mid-2015. This represents the German National Library's response to the growing demand for freely available metadata.
