APIs of the Staatsbibliothek zu Berlin - Preußischer Kulturbesitz*

*(to the extent currently implemented)

Programmatic access to the digitised collections and digitised newspapers of the Staatsbibliothek zu Berlin - Preußischer Kulturbesitz (SBB) is currently possible via two distinct APIs.

1. Digitised collections: OAI-PMH

Retrieval of metadata for objects in the digitised collections is established by use of the The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) standard. A wide range of client applications for OAI-PMH in numerous programming languages are freely available on the web.

The base URL for the OAI-PMH endpoint of the digitised collections of the SBB is
