The Teaching Company

The Teaching company commissions top collage professors to prepare great courses that they publish on DVD, VHS, CD, Audiotape, Audio file and printed format. The courses are grouped in 9 categories; Business and Economics, Fine Arts and Music, History - Ancient and Medieval, History - Modern, Literature & English Language, Philosophy & Intellectual History, religion, Science and Mathematics, and Social Sciences. Every course goes on sale at least once a year and advertised in The Economist magazine or at their web site. You can also check your local library for these great courses that I strongly recommend.
