Online Catalogue of Musical Sources
A new music catalogue has been available online free of charge since June 2010. The catalogue was made possible through cooperation between RISM, the Bavarian State Library (Bayerische Staatsbibliothek) and the State Library of Berlin (Staatsbibliothek zu Berlin).
From 1997 to July 2002, a subscription database version of Series A/II was available through a joint venture of the RISM Zentralredaktion and the U.S. RISM Office at Harvard University. Beginning in 2002, a second subscription database, updated biannually, was offered by the National Information Services Corporation (NISC). Since 2008, this service has been provided by EBSCO publishing.
