Prelinger Archives
Prelinger Archives was founded in 1983 by Rick Prelinger. Over the next twenty years, it grew into a collection of over 60,000 "ephemeral" (advertising, educational, industrial, and amateur) films. In 2002, the film collection was acquired by the Library of Congress, Motion Picture, Broadcasting and Recorded Sound Division. Prelinger Archives remains in existence, holding approximately 4,000 titles on videotape and a smaller collection of film materials acquired after the Library of Congress acquisition.
