There are over 50 different digital collections specific to music and the performing arts. Find them through the Library's Digital Collections website and select "Music Division."
These digital collections include thousands of pieces of sheet music on innumerable topics, liturgical chants that are nearly 1,000 years old, books about music from before 1800, and many other manuscript and printed scores.
Many of the Music Division's holograph music manuscripts (written in the composer's own hand) have also been scanned and made available to view and download on the Library's website. Composers with several manuscripts available online include Ludwig van Beethoven, Johannes Brahms, Franz Liszt, Arnold Schoenberg, and Igor Stravinsky. Find them by searching the composer's name and limiting results to "Notated Music" or by searching the Music Treasures Consortium digital collection.
