1 The Journal hopes occasionally to publish review essays bringing to our readers’ attention significant international law scholarship appearing in major languages and legal traditions outside the ambit of the United States and England. This is first effort to do so.

2 In the context ofthe Max Planck research project on the history of German international law in the twentieth century, headed by Michael Stolleis, a number of recent monographs have been published in German—inter alia, Bernhard Roscher, Der Briand-Kelloggpakt Von 1928: Der “Verzicht Auf Den Krieg Als Mittel Nationaler Politik” Im Völkerrechtlichen Denken Der Zwischenkriegszeit (2004), And Stefanie Steinle, Völkerrecht Und Machtpolitik: Georg Schwarzenberger (1908-1991) (2002).
