The Morgan's musical manuscript collection is second in size only behind the Library of Congress. These include autographed and annotated libretti and scores from Beethoven, Brahms, Chopin, Mahler and Verdi, and Mozart's Haffner Symphony in D Major. The collection also contains the scraps of paper on which Bob Dylan jotted down "Blowin' in the Wind" and "It Ain't Me Babe". It also contains a considerable collection of Victoriana, including one of the most important collections of Gilbert and Sullivan manuscripts and related artifacts.
