i pulled all my college books off of the library of Tor for free...it was great. there was a whole bunch of kool shit...also seriously sinister criminal activity (The Joe Biden kind). ..and the sinister stuff was getting more prevalent around 2012 and even the Tor developers where telling us to take alot of extra precautions when using their network because world governments where very upset they couldnt see what was going on in there... I bailed from Tor about then.
