There seem to be a wealth of online resources for learning lisp. If you were to recommend a single online book (or one in a dead tree format) to someone with programming skills, which one would it be?

Here's a few resources I'm familiar with -

* Practical Common Lisp - http://www.gigamonkeys.com/book/ * Successful Lisp - http://www.psg.com/~dlamkins/sl/cover.html * SICP lectures by Abelson & Sussman - http://www.swiss.ai.mit.edu/classes/6.001/abelson-sussman-lectures/ * On Lisp by PG - http://www.paulgraham.com/onlisptext.html

* Teach yourself Scheme in FixNum days - http://www.ccs.neu.edu/home/dorai/t-y-scheme/t-y-scheme.html * The Scheme Programming Language - http://www.scheme.com/tspl3/
