The United States National Film Preservation Board is the board selecting films for preservation in the Library of Congress' National Film Registry. The National Film Registry is meant to preserve up to 25 "culturally, historically or aesthetically significant films" each year; to be eligible, films must be at least 10 years old.
The National Film Preservation Board was established by the National Film Preservation Act of 1988, reauthorized in 1992 for four years, and reauthorized again in 1996 for seven more years. The law also created the non-profit National Film Preservation Foundation, which is affiliated with the National Film Preservation Board but raises money from the private sector.
