Historic sounds preserved in library

Astronaut Neil Armstrong's first words from the moon join speeches by President Woodrow Wilson and General Douglas MacArthur and songs by Al Jolson, Muddy Waters and rock band Nirvana that are among 50 recordings being set aside for special preservation by the Library of Congress.

The list has been entered into the library's National Recording Registry.

There is plenty of music, from Victor Herbert's Gypsy Love Song of 1898 to Nirvana's album Nevermind of 1991.
