The Recorded Sound Reference Center provides access to the commercial and archival audio holdings of the Library of Congress. The collection dates from 1926 when Victor Records donated over 400 discs to the Library's Music Division to supplement its print and manuscript holdings. In the custody of the Motion Picture Broadcasting and Recorded Sound Division since 1978, the collection has grown to include over 2 million items encompassing audio formats from cylinders to CDs. The holdings complement the field recordings of the American Folklife Center and the moving image collections served in the Motion Picture and Television Reading Room.
