Great, it looks like a good book and a valuable resources. It's a shame about the publishing situation. I've been interested in Lisp and scheme for some time, but haven't found a way to learn it by accomplishing something with Lisp yet. I'm looking forward to finding a project. "Oh, and one more thing: It's not quite true that no mass market product uses Lisp. Microsoft's "Bob" environment for naive computer users was developed (and delivered) in Lisp." Okay, I'm sold! But really, MS was using Lisp in the 90s?
