The German National Library fulfils its role as the national bibliographic information centre of the Federal Republic of Germany on the basis of new acquisitions through legal deposit copies. On a division of labour basis, processing occurs only once for both locations. Publishers supply two deposit copies of monographs and periodicals to the location responsible for them. Responsibility is organised by regional principle: the Leipzig site of the German National Library processes all publications from the federal states Berlin, Brandenburg, Mecklenburg-Western Pomerania, North Rhine-Westphalia, Saxony, Saxony-Anhalt and Thuringia. The Frankfurt site is responsible for the states of Baden-Wuerttemberg, Bavaria, Bremen, Hamburg, Hesse, Lower Saxony, Rhineland Palatinate, Saarland and Schleswig-Holstein. After processing, the second copy is supplied "ready for storage" to the other library for use and archiving.
In addition, single deposit copies of all translations from the original German published abroad are submitted to Leipzig in cases where the licence has been issued by a German publisher who is based in Germany, as the owner of the original distribution rights (DNBG Art. 14 para. 2).
The works published in German abroad which also fall within the collection mandate of the German National Library, the translations of German originals not submitted as deposit copies, and foreign-language works about German subjects are submitted as gifts, as purchases or in exchange. Single copies of these publications are processed by the German National Library in Leipzig.
All publications are catalogued at the location specified in the "Rules for alphabetical cataloguing" (RAK). The content cataloguing is based on the "Rules for the subject heading catalogue" (RSWK) and the "Dewey Decimal Classification" (DDC) system. The central cataloguing system used is ILTIS (integrated literature, sheet music and sound recording information system).
In addition, the German National Library makes use of authority files, in whose development and maintenance it is actively involved (GND).
The processing of sheet music and sound recordings is carried out exclusively in the German Music Archive (Deutsches Musikarchiv). After processing, it supplies the second presentation copy to the sheet music and sound recording collection of the German National Library in Frankfurt for archiving.
