EPTIt's basically a miniature online library. They have transcripts of many famous books sorted by author. Really nifty.
MITWorld is another one of my more treasured bookmarks. It's a collection of video-recorded lectures and talks by professors and guest-speakers at one of the more prestigious universities in America.
You'll need a media player that can handle .ram files to enjoy the videos, but there's several free media players out there to download for watching in this format.
Hope you enjoy the links as much as I do.
