MIT OpenCourseWare 

By on

MITMIT OpenCourseWare (MIT OCW), available online at http://ocw.mit.edu, makes the MIT Faculty's course materials used in the teaching of almost all of MIT's undergraduate and graduate subjects available on the Web, free of charge, to any user anywhere in the world. MIT OCW can be considered a large scale, Web based publication of educational materials. Educators in the U.S. and the developing world utilize the materials for curriculum development, while students and self-learners around the globe draw upon the materials for self-study or supplementary use. With nearly 1,800 courses now available, MIT OCW is delivering on the promise of open
sharing of knowledge.

You can view the MIT OpenCourseWare at http://ocw.mit.edu.
