I'm about to learn Lisp and/or Clojure(Script). How does this book differ from for e.g Land of Lisp? I was planning to get my fingers dirty with some more light material before digging in the recommendations (PAIP, PCL, SICP).
PCL will teach you CL, how CL works, in clear language and examples.
Ultimately, though, I realized I prefer the Scheme family (especially Racket). CL is crufty and arcane, and I prefer the Lisp-1 model (this does come at a cost to macro ease of use, but I'm not yet a huge macro fanatic, and once you learn the harder Scheme/Racket macros they can do insanely great things).
For learning Scheme, SICP is the classic, and there's an interactive version of it. I also recommend the Little Schemer for getting yourself in the mindset of learning how to use recursion in clever ways.
For Racket, the go to choices are Realm of Racket (which you can think of as a more clearly written Racket version of LoL but with a slightly less interactive approach), and How To Design Programs (which is quite a lot to get through, being designed as a full year course in CS).
Later, I moved on to the Clojure books. Working through the Little Schemer was invaluable (and its bibliography is excellent too).
