Review title: Excellent, but hard to find
Product review: This is an excellent book, and if you understand it it will make you a better lisp programmer. See the other reviews here or search through the comp.lang.lisp archives for testemonials. Yes, it's _that_ awesome...but unfortunately On Lisp is out of print, and is really hard to find used copies of--probably because nobody wants to part with it. Furthermore, it doesn't look like Prentice Hall, or anyone else will be publishing it any more. Fortunately, Paul Graham has made this available in postscript and pdf forms on his website. It's missing a few figures, but will definitely be helpful for everyone who has been patiently waiting months for a copy. Thanks, Paul!
