The Recorded Sound Research Center provides access to the commercial and archival audio holdings of the Library of Congress. The collection, in the custody of the Motion Picture Broadcasting and Recorded Sound Division since 1978, has grown to include over 3.5 million items encompassing audio formats from cylinders to CDs.
These recordings include both modern-day recordings of silent film scores as well as archival recordings. For more information on using the resources in the Recorded Sound Research Center, consult their own research guide or contact them through Ask A Librarian.
