In February 2003, the "Deutsche Musikverlegerverband e.V." (DMV) in Bonn took over responsibility for the ISMN in the above-mentioned countries. Prior to this, the "MBV. Marketing- und Verlagsservice des Buchhandels GmbH" in Frankfurt, formerly known as the "Buchhändler-Vereinigung," had acted as the national agency. It had at the same time published the VLM (Music in Print), yet with limited success. A re-launch of this directory was initiated in 2002 by DE-PARCON based on the company's experiences with music database software and data administration. On the one hand, it is hoped that the cooperation between the DMV and DE-PARCON, both operating closely with the market for printed music, will be the key to continued development of the ISMN in Germany; and on the other hand, to the building of an effective database of printed music , turning this database into an indispensible tool for libraries and all parts of the supply chain.
