Common Lisp: A Gentle Introduction to Symbolic Computation

I finished reading this old (1989 !) but still cool book today. It is not so funny as "Land of Lisp" but it  has code to play tic-tac-toe ! And I am really impressed bcs "classical" recursive factorial function was introduced only in the middle of books at page 237

I am not crazy enough to use emacs so for all code samples and exercises I used LispIDE and ecl. It seems that this combination is not officially supported but it works fine - you just need to choose right ecl2.exe in Settings->Set Lisp path menu. The only drawback is that DOCUMENTATION function doesn`t work in my ecl version
