I am disappointed too. This looks like a very interesting book and there would be plenty of room on my bookshelf among the many Scheme, Common Lisp, and Clojure books that I have paid for and refer to frequently. Good documentation is hard to find and having a physical copy means that I it will be available to me for decades. Almost 20 years ago I picked up a hardbound copy of "The C++ Standard Library: A Tutorial and Reference" by Nicolai Josuttis and it is still something I love having within arms reach of my keyboard.
