Listening to our classes and lectures couldn't be more convenient. You can put them in your smart phone, or on a thumb drive that you plug into your car console. Some of our MP3 files are also on CDs for your convenience.

In 1970, people would routinely put $1.00 in the basket when they attended these lectures. That dollar in 1970 is now worth 16 cents in buying power today. We hope you won't mind our low download charges in choosing the lectures. They help pay for the many costs of offering the MP3 files.We do not have encryption on the files, still, we ask as a courtesy that you not share or give away the files you purchase here.
