I have three - "Programming Clojure" (PragProg), "The Joy of Clojure" (MEAP - Manning) and "Clojure In Action" (MEAP - Manning). There is the Apress book coming out soon, and I am yet to pick up the beta Of those 3 the PragProg and "Clojure In Action" seem to be the ones that most people are using to get up and running with Clojure. The PragProg is pre 1.0 (FYI). Both the above mentioned books look good. But I am especially impressed with the Joy Of Clojure by fogus (a HN'er) - From what I have read so far (which is the first 4 chapters in the MEAP) - they are taking a different approach to teaching Clojure. They are emphasizing the philosophy of Clojure - so they attempt to explain the "why" as well as the "how". Having played with some Clojure this definitely helps to bring somethings into perspective. I would recommend picking up the PragProg book (if for no other reason than it's the only complete Clojure book out there) and "The Joy of Clojure". I am eagerly waiting out the Apress book to see how it is. Hope that helped.
