Another of the aims of libraries is to preserve not only written materials, but recorded sound, too. In turn, this preserves our history and culture. The Library of Congress has released their 2012 choices for permanent preservation in the National Recording Registry.
Pink Floyd's “The Dark Side of the Moon”, which debuted 40 years ago this month, received the most nominations. Other popular tunes include: “The Twist” by Chubby Checker, “The Sound of Silence” by Simon & Garfunkel, and the soundtrack for “Saturday Night Fever” (the film was recently selected for preservation in the National Film Registry).
Radio broadcasts by Will Rogers, Jimmie Davis, and President Dwight D. Eisenhower were also among the 25 nominations.
