The University of Texas at Austin has assembled an index of free online course materials from around the world. This portal now includes filters for audio and video (here are the search results for all courses with audio and video). Be forewarned - many of the courses include nothing more that a syllabus, some seem like scams, and others take you to pages requiring an university ID to log-in. Nevertheless, World Lecture Hall is an opportunity to find free courses materials from universities other than those with formal OpenCourseWare programs indexed by the excellent OCW finder.
Although there is alot of garbage to filter through, there are some good nuggets in there. I plan to take a closer look at these Classics courses, this University of Delaware online ecommerce course, and the independent study school of law.
