Open Courseware is making it possible for anyone with an internet connection to find subject knowledge from many different academic institutions. The best part for knowledge seekers is that it is free and open to the public. Perhaps you would like to know about Quantum Physics or English Literature. There is a very good chance that lectures, notes, exams and class references will be available in a particular subject.
Operations Research is no different to Open Courseware. In fact there is an increasing amount of Operations Research, Management Science, Supply Chain, and Applied Mathematics available on the internet. The Open Courseware Consortium is one way to find open courses on the internet in Operations Research. The consortium themselves are trying to promote themselves with membership but to search for courses is free to the public by the institution. IEOR Tools has featured this in previous blog post about open courseware.
