The main challenge in implementing the MIT OCW initiative had not been faculty resistance, but rather, the logistical challenges presented by determining ownership and obtaining publication permission for the massive amount of copyrighted items that are embedded in the course materials of MIT's faculty, in addition to the time and technical effort required to convert the educational materials to an online format.[6] Copyright in MIT OpenCourseWare material remains with MIT, members of its faculty, or its students.[7]
