Lecture CDs

[Azorbz]

I'm not sure if this is the correct place to ask, but is there any way to purchase the old CD sets previously available from the Ayn Rand Bookstore? I'm aware that the audio is available on the ARI eStore, and on YouTube, but I was hoping to pick up some of the CDs.

 

In particular, I'm trying to find Objectivism By Induction by Dr Leonard Peikoff. I've managed to pick up a few from other sources (the Ford Hall Forum speeches on eBay, for example), but haven't found much.
