The best lisp book I have found to learn Lisp, while really understanding all that's happening underneath is "COMMON LISP: An Interactive Approach". Basically, there's no hand waving in this book. It doesn't teach you to have a lisp blog in five minutes doing copy paste of code you don't understand. It respects you as a smart learner, and makes you write the code, you learn doing stuff by yourself being smartly led by the author, and by the end of the book you have written a very complex piece of software with many advanced concepts and you understand more about lisp than you could have by following endless web tutorials. The book can be downloaded from: http://www.cse.buffalo.edu/~shapiro/Commonlisp/ http://www.cse.buffalo.edu/~shapiro/Commonlisp/ It is to me a vastly underrated resource for all people interested in Lisp.
