Interfaces
IIIF APIs
You can integrate the contents of the Bavarian State Library, which are provided in the IIIF standard, directly into web offers via the APIs (Application Programming Interface) without having to download and maintain the data yourself.
Please note: Commercial use of our digital copies may be subject to approval and fees. For more information on usage and possible fees, please refer to our FAQ.
The interfaces described below provide their responses with the Access Control Allow-Origin: * header, making it possible to use provided data directly in client-side JavaScript applications. The Bavarian State Library provides the IIIF Presentation API and the IIIF Image API. The former one delivers so called manifests of digital objects in JSON-LD format. Inside the manifests Image API endpoints for each facsimile image are referenced. An info.json file is available at each of these end points, which allows information about the image to be retrieved immediately.
Presentation API
You can use this interface to access the metadata of an object in JSON format, the so-called manifests. In addition to a range of bibliographic metadata (.metadata), you will find a data structure that lists all pages ('canvases') of an object (.sequences[0].canvases). Each of these canvas entries refers (under .images[0].resource.service[@id]) to the corresponding image API under which the image is accessible for the page.
If available, OCR (full text) for the page is linked under .seeAlso[@id] in hOCR format. Please note that there is a limit to the number of OCR downloads that can be made per 24 hours. Access to the Presentation API is unlimited.

Bavarian Digital Repository
The Bavarian Digital Repository (BDR) is developed to be a freely accessible interface for harvesting metadata about all digital representations produced by or in cooperation with the Bavarian State Library. BDR conforms to the OAI Protocol for Metadata Harvesting (OAI-PMH).
