Satow's Diplomatic Practice has always been the flagship of the literature on the subject. Under the continued far-sighted and scholarly leadership of Sir Ivor Roberts, the 8th edition brings up to date chapters of the last editions and adds chapters on contemporary challenges and on good and bad diplomacy. He has assembled, once more, a stellar group of contributors, who discuss not only diplomacy in bilateral relations, but also in international institutions. Thorough and superbly researched and written, it is the definitive authority, a must-read book for diplomats, academics, students and all those interested in international law and relations. I recommend it enthusiastically.
