The Internet Archive has partnered with BitTorrent to publish over 1,000,000 of its books, music and movies as legal torrents. It's a huge whack of legal content in the torrentverse, and a major blow to the schemes of entertainment execs to have the whole BitTorrent protocol filtered away to nothing on sight. From the Internet Archive's blog:
BitTorrent is the now fastest way to download items from the Archive, because the BitTorrent client downloads simultaneously from two different Archive servers located in two different datacenters, and from other Archive users who have downloaded these Torrents already. The distributed nature of BitTorrent swarms and their ability to retrieve Torrents from local peers may be of particular value to patrons with slower access to the Archive, for example those outside the United States or inside institutions with slow connections.
