National Film RegistryThe National Film Registry (NFR) is the United States National Film Preservation Board's selection of films for preservation in the Library of Congress. The NFR names to its list up to 25 "culturally, historically, or aesthetically significant films" each year, showcasing the range and diversity of American film. The Registry includes films ranging from Hollywood classics to orphan films. A film is not required to be feature-length, nor is it required to have been theatrically released. The Registry contains newsreels, silent films, experimental films, short subjects, films out of copyright protection, film serials, home films, documentaries, independent films, television films, and music videos. As of the 2012 listing, there are 600 films preserved in the Registry.
