In 1988, the U.S. Congress established the National Film Registry in the Library of Congress which annually recognizes twenty-five films from the United States based on their cultural, historical, or aesthetic significance. The National Film Registry represents a wide range of filmmaking, contexts, and histories from early cinema to contemporary films selected by the Librarian of Congress (in consultation with members the National Film Preservation Board) every December. Films inducted into the registry are preserved through the Library of Congress and with collaborative efforts from other archives, studios and copyright holders or individuals. The Academy Film Archive has preserved fifty-eight National Film Registry titles and holds over 648 National Film Registry titles.
