I just bought ePubs for your Raja Yoga Revisted (I usually study SRF material, but alternatives are good!) and Scheme 9 for Empty Space. Your web site is very nice, I loved the ‘Who am I?’ page. I have been using Lisp languages since 1978 but except for studying Peter Norvig’s Lisp in Python, I have never dropped below the abstraction layer into a Lisp implementation so I am looking forward to that.
