O'Reilly has recently made a Rough Cut of "
Clojure Programming" available by Chas Emerick, Brian Carper and Christophe Grand.
After a short introduction, it has chapters on functional programming, macros,
Java interop, datatypes & protocols, organizing & building Clojure projects, mathematics & data analysis, working with RDBMS (including using Hibernate with Clojure!), working with CouchDB, and building web applications.
I've added it to my collection of Clojure books and I'm really enjoying it. The chapter on working RDBMS has already proved useful in my day job.
