This year's list includes jazz, classical, folk, country, gospel, and pop recordings, as well as such miscellany as astronaut Neil Armstrong's 1969 broadcast from the moon and noises made by Asian elephants.

Among the jazz recordings added to the registry are Fats Waller's "Ain't Misbehavin'," Coleman Hawkin's "Body and Soul," Glenn Miller's "In the Mood," John Coltrane's "Giant Steps," and a recording of "The Girl from Ipanema" by Stan Getz, Astrud Gilberto, Joê£o Gilberto, and Antonio Carlos Jobim.

Classical recordings include a 1929 record of Rachmaninoff's Second Piano Concerto, performed by the composer and the Philadelphia Orchestra; a Boston Symphony performance of Prokofiev's Peter and the Wolf; an NBC Symphony Orchestra performance of Tchaikovsky's First Piano Concerto, conducted by Artuto Toscanini with Vladimir Horowitz as soloist; and a recording of the original cast of Virgil Thomson's Four Saints in Three Acts.

The Library of Congress separately announced that it had uncovered a previously unknown recording of pianist Thelonious Monk and saxophonist John Coltrane performing at Carnegie Hall, according to the Associated Press. The 55-minute tape was made by the Voice of America network in 1957.
