New acquisitions based on the Legal Deposit Regulation form the basis of the German National Library's work as the national bibliographic information centre of Germany. Immediately after releasing their publications, publishers and other organisations with distribution rights submit two deposit copies to the relevant site of the German National Library. Which site depends on the region in which the organisation is based: the Leipzig site processes all publications from Berlin, Brandenburg, Mecklenburg-West Pomerania, North Rhine-Westphalia, Saxony, Saxony-Anhalt and Thuringia. The Frankfurt site is responsible for Baden-Württemberg, Bavaria, Bremen, Hamburg, Hesse, Lower Saxony, Rhineland Palatinate, Saarland and Schleswig-Holstein. After being processed, one of the two copies is sent in "archivable" form to the other library for archiving and use.
One deposit copy of translations of German works which are published abroad (but licensed by a German publisher based in Germany who is the owner of the original distribution rights) must be submitted exclusively to Leipzig for collection and processing (DNBG Art. 14 para 2).
Works which are published abroad in German and which also fall within the collection mandate of the German National Library, the translations of German originals not collected as deposit copies, and foreign-language works about German subjects are collected as gifts, as purchases or as swaps. Single copies of these publications are also collected and processed by the German National Library in Leipzig.
Sheet music and sound recordings are processed by the German Music Archive of the German National Library at the Leipzig site. After cataloguing the works it forwards one copy for archiving to the Frankfurt site of the German National Library.
All publications undergo descriptive and subject cataloguing at the relevant site. Descriptive cataloguing is currently based on the Rules for Alphabetical Cataloguing (RAK), although from 1 October 2015 this will change to Resource Description and Access (RDA). Subject cataloguing is based on the Headword Cataloguing Rules for Subject Cataloguing (RSWK) and Dewey Decimal Classification (DDC). The controlled vocabulary for cataloguing ist based on the Resource Description and Access (RDA) and the Headword Cataloguing Rules for Subject Cataloguing (RSWK) codes and is provided in the Integrated Authority File (GND) which the German National Library is involved in developing and maintaining. The central cataloguing system used is ILTIS (Integrated literature, sheet music and sound recording information system).
