Have a few courses in mind that you think are awesome and would fit in this list? Feel free to send a pull request. However, do note that I'm not keen on adding popular courses (such as MOOCs / MIT OCW) as there are services like ClassCentral doing a great job of aggregation. This list is ideally for courses which are relatively unknown and make their material (assignments, lectures, exams etc.) available online for free. When adding new courses to the various categories, please ensure that alphabetization (ex. CSCE 48 should be listed after CS 240) is maintained. This makes it easier for viewers to find what they are looking for.
