Integrated Authority File (GND)

Structure and characteristics

GND records contain a controlled heading, variant forms, dates or qualifiers, and a stable identifier. Records cover several entity types — individual persons, corporate bodies, subject terms, conferences and works — and are encoded for exchange in formats used in bibliographic systems and the semantic web. The dataset is organized to support authority control, disambiguation and machine-readable linking between catalogues and external resources.

History and governance

The GND was created by integrating pre-existing German-language authority files into a single, harmonized system and is managed by the German National Library (Deutsche Nationalbibliothek) in cooperation with library networks and partner institutions in German-speaking Europe. National libraries, regional consortia and specialist cataloguing centres collaborate on updating, quality control and policy. Relevant institutions and communities contribute to maintenance and see the file as a shared infrastructure resource (library networks, cataloguing projects).

Uses and importance

Libraries use the GND for bibliographic description, authority control and subject indexing; archives and museums increasingly reuse GND identifiers to link person and corporate body names in finding aids and collection records. Because GND identifiers are stable and machine-actionable, they facilitate data linking across systems, integration with international authority services and enrichment of discovery platforms. Institutions may access GND data through data dumps, query services and integration tools (library services, archival use).

Access, license and technical notes

The GND is published under a permissive public-domain dedication (Creative Commons Zero, CC0) to encourage reuse and linking. Its distribution formats support both traditional cataloguing standards and semantic web technologies, enabling mapping into RDF and use in knowledge graphs. Developers and cataloguers can consult documentation, APIs and download services offered by participating institutions and projects (museum integrations, official documentation).

Key features and distinctions

• Shared, multilingual-aware authority control for names, subjects and corporate entities.
• Stable, unique identifiers intended for long-term linking between records and external datasets.
• Cooperative governance model led by the German National Library and regional partners.
• Open licensing (CC0) and technical support for linked data and catalogue interoperability.

The GND serves as a national and international point of reference for bibliographic and cultural heritage institutions wishing to harmonize name and subject data and to participate in linked open data networks.
