A little bit of self-congratulation: the Association for Continuing Legal Education has given the 2013 Award of Outstanding Achievement to International Judicial Assistance: Serving Process, Obtaining Evidence, Enforcing Judgments and Awards (MCLE 2012). The book is a nuts-and-bolts guide to some key topics in international judicial assistance rather than a treatise or a scholarly work, but I hope it has come in handy for lawyers in a pinch. You can buy the book at the MCLE website. (Full disclosure: I get no royalties).
