The Library of Congress is announcing a plan for saving the nation’s history in recorded sound under a mandate from Congress. The library already saves key audio selections each year, but many other recordings are being lost due to a lack of storage capacity, changing technology and disparate copyright laws. Researchers say more than half of the oldest recordings, including audio from George Gershwin, Frank Sinatra and Judy Garland have already been lost. (AP Photo/Jose Luis Magana, File)
