The first edition of this book became a standard work in the field, and it has been extensively revised and updated for the second edition. It is prepared with assistance from the official Depositaries of the various international agreements, and is an essential reference book for statesmen and diplomats, lawyers, journalists, and students of international relations and law. From reviews of the first edition: `Roberts and Guelff rely on the documents to speak for themselves, and are right to do so. Their becoming generally available in this neat and usable form is an event of much importance for all who take a serious interest in humanitarian law and endeavour, and the limitation of men's violence towards men.'New Society
