This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
Pragmatic publishing has a monthly magazine that I read regularly and this month they have a special issue on Clojure. It is out now (http://pragprog.com/magazines) !
Haven't had time to read much yet but there's an intro article and what seems to be a bit deeper articles.
