For two decades, OpenCourseWare has been sharing MIT teaching materials with the world. In that time, OCW has become a robust, free educational resource thousands of people rely on every day to improve their knowledge, circumstances, and communities.

As we mark 20 years of OCW, we are celebrating the community of learners, MIT faculty, and collaborators who have made OCW a change agent for education at MIT and around the world, and helped launch the modern open education movement.
