Structure

As with the SWD and PND, the "Rules for Alphabetical Cataloguing" (Regeln für die alphabetische Katalogisierung or RAK-WB) are used. They stipulate, amongst other things, what counts as a corporation. These include, inter alia, local authorities and associations such as firms and club

In addition to names (index terms and synonyms) of individual corporations, GKD data files contain links to parent bodies as well as earlier and later names.

GKD records are uniquely identified by an ID number, the GKD number. The GKD number consists of digits, the last being a check digit, which can also be 'X' (for 10). The number ranges are divided into quotas by library network, so that, for newer records, it can be determined in which network they were created.

The GKD, like the PND and SWD, is available to information systems in libraries (usually library networks) and other areas via the DDB file on a standard CD-ROM or through a Z39.50
Z39.50
