The Internet Archive

The Internet Archive is a digital library with the stated mission: "universal access to all knowledge." It offers permanent storage and access to collections of digitized materials, including websites, music, moving images, and books. The Internet Archive was founded by Brewster Kahle in 1996. The collection has grown into the world's largest online library, offering 10 petabytes of archived websites, books, movies, music, and television broadcasts.
The most famous part of this archive is the Wayback Machine, a digital archive of the World Wide Web and other information on the Internet.

The Internet Archive is now offering over 1,000,000 torrents including its live music concerts, the Prelinger movie collection, the librivox audio book collection, feature films, old time radio, lots and lots of books, and all new uploads from our patrons into Community collections (with more to follow). Read here for more information about these torrents.
