Recorded sound has played an important role in the cultural, social, and political life of the United States. Recognizing this, and concerned about the preservation of and long-term access to the national sound heritage, the U.S. Congress enacted the National Recording Preservation Act of 2000 (Public Law 106-474). This law directed the National Recording Preservation Board (NRPB), under the aegis of the Library of Congress (LC), to conduct a study and issue a report on the current state of sound-recording archiving, preservation, and restoration activities and to recommend standards for access to preserved-sound recordings by researchers, educators, and other interested parties.
