There was a predecessor of WebDewey Deutsch and WebDewey Search: MelvilClass and MelvilSearch. We migrated the whole data to DDC MARC 21 and switched to WebDewey Deutsch and WebDewey Search in 2012. There will be no further German print edition, WebDewey Deutsch is the only tool for classifying with DDC; DDC updates are published there continuously. DDC Deutsch is used in Germany, Austria and Switzerland, partly for shelving, but mainly for searching DDC-classified works via online catalogs. Most of the DDC-classified data is made by the DNB and supplied from there to the library networks (Verbünde) and individual libraries in the DACH countries. Notations of the DDC Deutsch serve as a basis for the DDC Subject Categories (used to organize the Series in the Deutsche Nationalbibliografie), as well as for DDC Short Numbers, which are used in machine-based cataloging. |
