I've been trying to find out where I might be able to purchase copies of recordings of Huxley's MIT Lectures or Santa Barbara Lectures. I've tried contacting Big Sur Tapes, but they appear to be out of business, even though their website is still up. I tried Amazon.com but after 6 months they said the MIT Lectures were unavailable through them. Can anyone help me out? I'd be happy to purchase copies from private sellers as there don't seem to be any vendors out there that I can find. Any info or suggestions would be greatly appreciated. Thanks!
