RISM: International Inventory of Musical Sources
The International Inventory of Musical Sources (RISM) aims to comprehensively document the world’s musical sources of manuscripts or printed music, works on music theory and libretti stored in libraries, archives, monasteries, schools and private collections. The online-catalogue offered here contains around 700,000 references almost exclusively to music manuscripts. These records pass on to posterity the works of some 25,000 composers. The sources are preserved in the libraries and archives of 32 countries. The RISM online catalogue currently contains over 1.1 million music incipits.
