This is readable and useful. It provides a good introduction to Clojure, and scores quite well on something that I judge a book on - which is how easily I can find information in it afterwards. The index so far has listed the keywords I have looked up and key functions are highlighted on the page which helps you find what you're looking for. It doesn't cover web development - for which I had Clojure in Action to help with.
