The U.S. Library of Congress in Washington, D.C., is the unofficial national library of the United States.  Officially, it’s just the library of the U.S. Congress, but they do far more than that.  The National Recording Preservation Act of 2000, a U.S. law, mandated the creation of the National Recording Preservation Board.  That august-sounding body is responsible for “ensur[ing] the survival, conservation, and increased public availability of America’s sound recording heritage.”  They are responsible for the National Recording Registry, an annual list of recordings worthy of preservation.  The 2009 list just came out (yeah, they’re a little behind).  Iry LeJeune’s 1948 recordings of Evangeline Special and the Love Bridge Waltz are on the list (LeJeune’s Definitive Collection from the Louisiana Music Factory).  This honor is shared with such wonderful American recordings as “Tutti Frutti,” Little Richard; “Smokestack Lightning,” Howlin’ Wolf; “When You Wish Upon a Star,” Cliff Edwards; and “Coal Miner’s Daughter,” Loretta Lynn.   The Hollywood Reporter has an article on the new list, as does the UPI.
