[Wlug] Books Of Lisp

Hi. Well, I figure since Lisp is such an important language, especially in GNU/Linux systems (favorite of Stallman afterall) I should pose this question to this group. Basically I'm interested in learning Lisp and was wondering if anyone has some favorite or recommended books that describe the syntax of Lisp. Additionally books related to introductory artificial intelligence work, with algorithms, design issues, et cetera, especially books with example Lisp code would be very welcome. Thanks. - Carlton Stedman II
