Gemeinsame Körperschaftsdatei followed by Gemeinsame Normdatei
The Gemeinsame Körperschaftsdatei or GKD (translated as Corporate Bodies Authority File) is a German authority control for the organisation of corporation names (corporate bodies) from catalogues. It is used mainly for documentation in libraries. Like the Schlagwortnormdatei (SWD) (English: Subject Headings Authority File) and the Personennamendatei (PND) (English: Name Authority File), the GKD is looked after and updated by the German National Library (DNB), the Bavarian State Library, the Berlin State Library and, since 1997, the Austrian National Library, several library networks taking part. The responsible editor is the State Library in Berlin. The GKD was created in the 1970s from the catalogue data of the Zeitschriftendatenbank (ZDB). In April 2004 it contained more than 915,000 records.
Since April 2012 GKD, SWD and PND are part of the Gemeinsame Normdatei (GND) (English: Integrated Authority File).
