From the June 2011 Library of Congress Information Bulletin (http://www.loc.gov/loc/lcib/1106/jukebox.html):
“The Library of Congress on May 10 launched the “National Jukebox,” an interactive website that allows users to play thousands of historic sound recordings—many of them unavailable to the public for more than a century.
The National Jukebox provides access to more than 10,000 out-of-print recordings of opera, popular music, comedy, religious music and political speeches produced by the Victor Talking Machine Co. in the first decades of the 20th century.”
