Music Division Collections at the New York Public Library"The Music Division is one of the world's preeminent music collections--documenting the art of music in all its diversity - classical and opera as well as the whole spectrum of popular music including spirituals, ragtime, jazz, musical theater, film, rock and world music. While the division contains many scores and manuscripts from centuries past, its curatorial mandate is an activist one, placing major emphasis on capturing the creative output of contemporary composers."
