We've recently restructured our website in order to make it more user-friendly.  As a result of this restructuring our directory listings may differ from older listings stored on internet search engines.  These files are still available on our site and can be found using our search box located on the left-hand side of this screen.

In the meantime, sorry for any inconvenience caused by the relocation of these documents.  And thank you for your interest in The Great Courses by The Teaching Company.  If you have any questions, please contact us by email at custserv@teachco.com or by phone at 1-800-TEACH-12 (1-800-832-2412).
