The National Recording Registry is a list of sound recordings that are culturally, historically, or aesthetically important, and/or inform or reflect life in the United States. The registry was established by the National Recording Preservation Act of 2000, which created the National Recording Preservation Board, whose members are appointed by the Librarian of Congress. The recordings preserved in the United States National Recording Registry form a registry of recordings selected yearly by the National Recording Preservation Board for preservation in the Library of Congress. The National Recording Preservation Act of 2000 established a national program to guard America's sound recording heritage. The Act created the National Recording Registry, The National Recording Preservation Board and a fund-raising foundation. The purpose of the Registry is to maintain and preserve sound recordings and collections of sound recordings that are culturally, historically, or aesthetically significant. Beginning in 2002, the National Recording Preservation Board has selected recordings nominated each year to be preserved. The first four yearly lists each had 50 selections. Since 2006, 25 recordings have been selected annually. As of 2018[update], a total of 525 recordings have been preserved in the Registry. Each calendar year, public nominations are accepted for inclusion in that year's list of selections, which are announced the following spring. Each yearly list typically includes a few recordings that have also been selected for inclusion in the holdings of the National Archives' audiovisual collection.
