Biblissima Authority Files

Total number of items in the authority files: 396,754

This platform provides Biblissima's authority file in the form of structured data. Its realization is part of the Biblissima+ programme, Observatory of Written Cultures, from Clay to Print (2021-2029). It follows Biblissima, Observatory of the written heritage of the Middle Ages and the Renaissance from the 8th to the 18th century (2012-2021).

These authority files are based on data collected and processed within the framework of the Biblissima+ programme.
They form the backbone of the Biblissima portal and the prototype IIIF Collections of Manuscripts and Rare Books.
They have been set up in order to identify, disambiguate, harmonize and align named entities from a wide range of data sources (digital libraries, catalogues and specialized databases on manuscripts and early printed books). This effort has been ongoing since the beginning of Biblissima in 2013.

For any request, or if you want to contribute, you can contact us at team@biblissima-condorcet.fr
Disclaimer: In its first phase, this platform is designed as a tool for managing, publishing and exposing the Biblissima authority files. Its primary goal is to create a hub of identifiers and structured data, that is accessible, interoperable and reusable for other projects.
This hub plays a central role in the interoperability of the resources processed within the framework of Biblissima, while allowing other projects to benefit from the work of reconciliation and harmonisation carried out in this direction. The data is indeed accessible in an automated way by various mechanisms intended primarily for machines (see below Data access and API).
Nevertheless, developments are planned to improve the user interface, the full-text search, and to offer easier browsing and querying modes.
