The MPAL Historic US Sheet Music Collection is comprised of almost 100,000 pieces of music, including a diversity of material from popular songs to art songs for piano or voice and piano. In many cases there are duplicate copies of pieces when there are differences in the content and/or the cover art. The dates included in the collection range from the early 1800s to the mid 1990s.
This collection is separate from the modern printed music editions found in our online library catalog, so you have to search for these materials separately.
To search the collection, start from our page on the University of Illinois's Historic US Sheet Music Collection.
Another tool you may want to explore if you are looking for historic sheet music is the Sheet Music Consortium!
The Sheet Music Consortium is a group of libraries working toward the goal of building an open collection of digitized sheet music using the Open Archives Initiative Protocol for Metadata Harvesting. Harvested metadata about sheet music in participating collections is hosted by UCLA Digital Library Program, which provides an access service via this metadata to sheet music records at the host libraries.
Much of the material is digitized and the site features virtual collections to help you browse!
