American Silent Feature Film Database
From the report “The Survival of American Silent Feature Films: 1912-1929”

The era of the American silent feature film lasted from 1914 to 1929. During that time filmmakers established the language of cinema, the motion pictures they created reached a height of artistic sophistication, and these films with their recognizable stars and high production values spread American culture around the world. Silent feature films disappeared from sight soon after the coming of sound, and many vanished from existence.
The database represents the first comprehensive survey of the survival of American silent feature films. It contains information on the nearly 11,000 U.S. feature films released between 1912-1929, and holdings information about 3,300 of those titles for which elements are known to exist.
The American Silent Feature Film Database is a cooperative project of the Library of Congress Packard Campus for Audio Visual Conservation and the International Federation of Film Archives (FIAF).
