Classic U2 Album Preserved In US Library
U2's The Joshua Tree has been selected for long-term preservation at the US Library of Congress in Washington DC.
The 1987 classic is among 25 works to be included in the National Recording Registry.
Every year since 2006 songs or albums are chosen for their cultural, historical or aesthetic importance.
Linda Ronstadt's Heart Like A Wheel and the Everly Brothers' Cathy's Clown have also been included.
Curator Matthew Barton said U2's sound, though not explicitly religious, has influenced and been combined with Christian rock in some churches, including the song, I Still Haven't Found What I'm Looking For.
Ronstadt said she was surprised to learn her album had been selected for safekeeping at the library, but it was nice to have a distinction.
She added that being in the company of the Everly Brothers in the library's recording archive was a special thrill.
The star's hit When Will I Be Loved was written by Phil Everly.
As of 2013 a total of 400 recordings have been preserved in the Registry.
