Classic records by The Bee Gees and Simon & Garfunkel are among the new entries picked for entry into the Library of Congress' National Recording Registry.

Each year, the Library of Congress selects for the Registry a handful of songs and albums that have been judged to be "cultural, aesthetic and/or historic American treasures."  This year, The Bee Gees' 1977 soundtrack for Saturday Night Fever and Simon & Garfunkel's 1966 studio effort, Sounds of Silence, are two of the 25 chosen recordings.

For many years the biggest-selling soundtrack of all time, before it was eclipsed by The Bodyguard, Saturday Night Fever topped the charts for 24 straight weeks, won several Grammys and spun off a string of hits.  It also helped popularize the disco phenomenon worldwide.

Sounds of Silence, meanwhile, was the famed folk-rock duo's second album, and included memorable classics like "The Sound of Silence" and "I Am a Rock."

Other new entries into the Registry this year include Pink Floyd's The Dark Side of the Moon, Cheap Thrills by Big Brother & the Holding Company -- featuring Janis Joplin on vocals -- and The Ramones' self-titled 1976 debut album.
