> Each and every course at MIT has put up all their educational documents including slides, exercises, tests, audio, video, schedules etc for free. Many courses also include video and other multimedia artefacts. Just to prevent readers from taking that statement literally, only a small minority of courses offer all these materials. (e.g., see [1]--you can see by the icons on the left which materials are available for which courses.) Most only offer lecture notes, and even those are generally very incomplete. What MIT has done with OCW is outstanding, and I personally have learned a lot from many courses already, but they still have quite a ways to go to meet such a comprehensive claim. More funding and enthusiasm for the effort is still very much needed. [1]: http://ocw.mit.edu/courses/mathematics/ http://ocw.mit.edu/courses/mathematics/
