Audible certainly makes it easier for subscribers to listen to audiobooks. We are gradually moving our general collection of Jim Weiss Audiobooks to Audible. You can still purchase these audiobooks as CDs and MP3s from our webstore. Most of these audiobooks can also be purchased through other vendors in both CD and MP3 format.
The Story of the World audiobooks are not moving to Audible at this time. However, you can purchase the CDs or MP3s from our webstore, and you can get the CDs from other vendors.
Why do we not put The Story of the World audiobooks on Audible? We have a few reasons.
Audible/Amazon's terms and conditions remove too much control from the publisher re: content and pricing. Putting our books on Audible would contractually limit our ability to offer our summer-sale deep discounts--which benefit all our customers, those who do and those who do not subscribe to Audible.
