Leslie Lundquist, a co-worker of mine here at Electric Communities, together with Dan Lynch from Cybercash & Interop fame, has written a book called _Digital Money: The New Era of Internet Commerce_. It should appear in stores "real soon now"; it can be ordered right now from any book store for $24.95. The book is intended as an overview of current and projected digital payment systems and commerce, and contains basic background information on the underlying technology. It is intended for the general reader: this is the kind of book a techno-weenie might buy for his or her manager to help them understand some of these issues. Note that this is a different book than _Digital Cash_, by Peter Wayner. I'm not in the loop on this, but this appears to be "one of those things" and not intentional on anyone's part.
