Review of the hardback: Advance praise: 'If Sean Murphy's first volume is an important resource for serious scholars and practitioners of international law, this second volume is all but indispensable. It covers a period in which United States practice has often been at the heart of extraordinary ferment in international law, from its encounters with the jus as bellum and the jus in bello, to the increasing number of judicial and arbitral decisions on international trade and investment. With a new generation of lawyers and judges voicing dissatisfaction with the instrumentalism of some secondary sources and demanding hard evidence of state practice to establish the existence of international obligations, a coherent presentation of primary sources by an author with extraordinary breadth of knowledge, interest and experience takes on ever greater importance. That Professor Murphy has been willing and able to meet this need without the direct government support that characterized such efforts in the past (and still characterizes them in other countries) is a tribute to his consummate dedication and skill. We are all in his debt.' Bernard H. Oxman, Co-editor in Chief, , American Journal of International Law.
