You can download Paul Graham's out-of-print book On Lisp. I found out about this from an interesting weblog called "Everything Burns" (http://jimfl.tensegrity.net/), which had this to say about it: <quote> I esteem OnLisp to be one of the most well-written, compelling books I have encountered on any topic in computing. This is no mean praise considering various works by one Stanford Professor name of Knuth. You don't really have to care much about Lisp or its variants to enjoy this book, though you should, at least, be able to tolerate topics which arise from the peculiarities in Lisp-shaped languages. Familiarity with Lisp will serve a programmer in any language anyway. Sadly, OnLisp is out of print, but you can download it free of charge. You will be missing only the weight of the dense paperback in your hands, the attractive cover, and the few figures sprinkled throughout. </quote> http://www.paulgraham.com/onlisptext.html --Dethe -- Dethe Elza (delza@burningtiger.com) Chief Mad Scientist Burning Tiger Technologies (http://www.burningtiger.com) Weblog: http://livingcode.manilasites.com/
