Sussman's "Structure and Interpretation of Computer Programs"

(MIT Press, 1984; ISBN 0-262-01077-1), an excellent computer

science text used in introductory courses at MIT. So called

because of the wizard on the jacket. One of the bibles of

the LISP/Scheme world. Also, less commonly, known as the
