[Updated 12-30-2019 - Yeah, sometimes I take my time about these things. Got stuff to do and a would-be dictator to derail. If it bothers you to wait a little bit, go get yourself a date or something...]
This is a comprehensive listing of all films selected for inclusion in the National Film Registry since 1989. Not surprisingly, due to the fact that the Registry goes beyond just popular feature films to include the widest variety of culturally significant documentaries, animation, experimental films and short subjects, that some more obscure titles often don't appear in the TCMb database until added later.
A new list of 25 selections to be added to the National Film Registry for that year is announced by the end of December. To nominate films to be added to the National Film Registry for the next round, visit www.loc.gov/programs/national-film-preservation-board/film-registry/nominate/
