Rick Prelinger has had a hybrid career collecting and making films from ephemeral archival material since 1982. He began by collecting advertising, educational, industrial, and amateur films that were often thrown away. His collection grew to over 60,000 titles now housed at the Library of Congress. Prelinger sees his role as a "meta-archivist" focused on access and public history. He has gone through stages of viewing archival films from valuing every film, to being seduced by their style, to seeing them as evidence of social and cultural contexts or just as peripheral evidence without historicity.
