Among the many milestones we will celebrate during the Institute’s 150th anniversary next year, I am particularly proud of the tenth anniversary of MIT OpenCourseWare, the start of which was announced on the front page of The New York Times on April 4, 2001. Since the announcement, MIT has published materials from more than 2,000 courses, presenting the undergraduate and graduate curricula from all 33 of MIT’s academic departments through the OCW Website (ocw.mit.edu). By the anniversary, these materials will have been visited more than 100 million times by an estimated 70 million individuals from nearly every country. More than 200 other universities around the world have joined MIT in publishing their course materials freely and openly, and have collectively published materials from more than 13,000 courses. This dynamic community, the OpenCourseWare Consortium, will gather on the MIT campus shortly after the anniversary to look back at the movement’s first 10 years and look forward to the next decade.
