Forrest Gump, Bambi and The Silence of the Lambs are among the titles chosen for preservation in the Registry's archive based on cultural, historic and aesthetic significance.
Billy Wilder's The Lost Weekend, John Cassavetes' Faces and Robert Rodriguez's El Mariachi are also among the annual selections. This year's additions bring the library's total to 575.
The Library of Congress's James Billington said: "These films are selected because of their enduring significance to American culture. Our film heritage must be protected because these cinematic treasures document our history and culture and reflect our hopes and dreams."
Alongside films and animations, the Registry includes documentaries, newsreels, music videos, movie ads and 8mm and 16mm amateur films.
