For those unaware, WorldTracker.org
was a website that hosted a massive set of files- mainly ebooks- providing information on pretty much every subject imaginable. Sadly it went down some time ago, but I've been in contact with a person who had almost all of it mirrored and set up a torrent for it. Enjoy!
Note to those without at least 550GB of available drive space- some torrent clients (such as Tixati) allow you to omit specific folders or files from the download.
