The online collections and exhibits prepared by the Library of Congress are generally considered authoritative and of excellent quality, and this new archive prepared by the Music Division within the Library of Congress is no exception. Containing over 62,500 pieces of historical sheet music, this archive is searchable by author, subject, and song title. Clicking on a particular work will allow visitors to view the entire song, all of which have been digitally scanned into the archive. Within the site, there are also other short online exhibits such as "Music Copyrighted in Federal District Courts, circa 1820-1860" and "In Performance-Choral Works from the Collection," which features some nice audio clips of the "Music for the Nation" Singers performing some of the music highlighted in this collection.
