RISM : Répertoire International des Sources Musicales is an international inventory of musical sources. Founded in 1952, RISM is a joint project sponsored by IAML (International Association of Music Libraries) and IMS (International Musicological Society). RISM strives for comprehensive documentation of extant primary musical sources worldwide: music manuscripts, printed music, writings on music theory, and libretti that are housed in libraries, archives, monasteries, schools, and private collections.
RISM establishes what exists and where it can be found.
