It's kind of like saying, I've heard of this wonderful book on learning French, can I use it to learn Spanish? They're similar languages, but not the same. The grammer is close, but different. The vocabulary is close, but different.<p>That being said, Land of Lisp is a fantastic way to get your feet wet in functional programming. I would highly suggest giving it a whirl. Learning Common Lisp will definitely help in learning Clojure. But you really need to look at it as two distinct steps towards your goal of learning Clojure.<p>There is also a new Clojure book coming out at the end of the month called the Joy of Clojure, which I'm really excited about. Currently the only two books out are Stewart Halloway's Programming Clojure, which is excellent. and Stuart Sierra's Practical Clojure, which is also very, very good. They are both focussed on Clojure 1.0, however, so you'll miss out on some of the features brought by 1.1 and 1.2. I own both, and can't recommend one over the other, though I might lean towards Practical Clojure purely for personal preference.
