Internet archive

The Internet Archive is a non-profit digital library with the stated mission of "universal access to all knowledge". It provides free public access to collections of digitized materials, including websites, music, moving images, and nearly three million public-domain books. As of October 2012, its collection topped 10 petabytes. In addition to its archiving function, the Archive is an activist organization, advocating for a free and open Internet.

The Internet Archive allows the public to upload and download digital material to its data cluster, but the bulk of its data is collected automatically by its web crawlers, which work to preserve as much of the public web as possible. Its web archive, The Wayback Machine, contains over 150 billion web captures.The Archive also oversees one of the world's largest book digitization projects.

The Internet Archive holds a collection of approximately 3,863 feature films.

Additionally, the Internet Archive's Moving Image collection includes: newsreels, classic cartoons, pro- and anti-war propaganda, and ephemeral material from Prelinger Archives, such as advertising, educational, and industrial films and amateur and home movie collections.
