Michael Jackson's 1982 smash record "Thriller" was added to the prestigious National Recording Registry on Wednesday.
So was a 1945 radio broadcast of then-New York Mayor Fiorello LaGuardia reading comics to children during a newspaper delivery strike.
Those were just two of 25 listings added to the registry, which is intended to keep track of and preserve sound recordings deemed "culturally, historically or aesthetically significant," according to the Library of Congress, which oversees the registry.
Under the National Recording Preservation Act of 2000, the librarian of Congress selects the 25 each year based on nominations from the public and from consultations with the National Recording Preservation Board, "which comprises leaders in the fields of music, recorded sound and preservation," the library said.
"Audio preservation constitutes a critical challenge," librarian of Congress James H. Billington said in a statement. "Much has already been lost, particularly in the field of radio. As the nation's library, the Library of Congress and NRPB are working to identify problems; come up with practical, consensus solutions; and assist other institutions facing these daunting challenges."
Country, blues and soul as well as pop music were represented by recordings of Kitty Wells ("It Wasn't God Who Made Honky Tonk Angels"), T-Bone Walker ("Stormy Monday"), Smokey Robinson and the Miracles ("Tracks of My Tears") and others.
A compilation of jazz recordings ("The Jazz Scene") includes works by the leading 20th century artists of the genre. Art Tatum's "Sweet Lorraine" was included separately, by itself.
With this latest round of selections, representing choices for 2007, the registry now totals 250 listings.
