Founded in 1983 by Rick Prelinger, Prelinger Archives is part of the Internet Archive, a nonprofit organization building a digital library of Internet sites and other cultural artifacts in digital form to promote universal dissemination of knowledge. The collection has grown over the years consisting of more than 60,000 films. In 2002, the Library of Congress, Motion Picture, Broadcasting, and Recorded Sound Division acquired the film collection. Prelinger Archives holds approximately 11,000 digitized and videotape titles (all originally derived from film) and an extensive collection of home movies, amateur and industrial films acquired since 2002. Prelinger Archives remains dedicated to collecting, preserving, and granting access to historical relevance films that haven’t been accessed elsewhere. Many of those films have been produced by hundreds of relevant US corporations, nonprofit organizations, trade associations, community and interest groups, and educational institutions.
