The Deutsche Digitale Bibliothek (DDB) is a cooperative project and exists due to the commitment of cultural and scientific institutions in Germany: Museums, libraries, archives, media libraries and other research institutions digitalise their collections, provide their data to the general public and thus make information and knowledge concerning cultural heritage available.

Why cultural and scientific institutions take part in the Deutsche Digitale Bibliothek

Cultural showcase for the world

Over 2,000 institutions have committed themselves to the idea of the German Digital Library and registered. The participating institutions establish the Deutsche Digitale Bibliothek as a cultural showcase for the world with their digitalised collections. As a result, they also contribute towards the democratisation of knowledge and resources.

Free and open access to cultural heritage in the Internet

The Deutsche Digitale Bibliothek makes the cultural heritage from German cultural institutions accessible for users in the Internet on a free, open and central basis. The collections of participating cultural institutions can also be published via the DDB’s application programming interface (API). With that said, the DDB’s data and methods can also be utilised by external applications (such as websites or mobile apps) and embedded into new contexts.

Deutsche Digitale Bibliothek cooperation project

Participating institutions also benefit from the professional exchange with many other institutions from all cultural sectors – in workshops, at conventions or in working groups on a national and international level. Many different institutions from all over Germany, supported by municipalities, federal states or the federal government, are partners of the Deutsche Digitale Bibliothek. The cultural map provides an up-to-date overview.


Cooperation partners also have the opportunity to provide their data to the European cultural portal known as Europeana  via the Deutsche Digitale Bibliothek.

The Archivportal-D: Sector-specific access to the archival information of the Deutsche Digitale Bibliothek

The Archivportal-D, funded by the DFG (German Research Foundation), is being realised as a sub-project within the framework of the Deutsche Digitale Bibliothek. The Archivportal-D uses the database of the DDB; in this way the data are visible in both portals by a single delivery and are, on the one hand, cross-linked over sectors but, on the other hand, also presented in an archive-specific context.
