Collected by Lester S. Levy and donated to Johns Hopkins University beginning in 1976, the Lester S. Levy Sheet Music Collection comprises American sheet music from the 18th through 20th centuries. The collection is particularly strong in its contents on the American Civil War, World War I, and sheet music dating from the 19th century, but the collection includes sheet music on a variety of topics. The database includes instructions and resources for researchers, educators, those working in media, musicians, collectors, and anyone else who may be interested. The database encourages musicians to use the sheet music, providing a “Performance View” and audio files for over 800 copies.
