The world has changed radically since 1989, when the General Assembly declared the period from 1990 to 1999 as the United Nations Decade of International Law. During that time, the international community claimed some major achievements as reflected by the adoption of conventions and treaties. This publication presents a collection of essays from legal advisers of States and international organizations, all of whom are among those committed to promoting respect for international law.

In 1983, when he was 80 years old, Leo Gross compiled 45 of his essays which had been published in scholarly journals and other collections from 1945 to 1984. The collection was published in two volumes by Martinus Nijhoff Publishers and Transnational Publishers in 1984, with a Preface by Judge Stephen M. Schwebel of the International Court of Justice. The collection has been out of print for some time. In response to many requests, the Publishers have now decided to issue a shorter, one-volume collection, the selection from the 1984 books having been carried out by Professor Alfred P. Rubin, who occupied the office adjoining that of Leo Gross in the Fletcher School for no less than seventeen years. In his impressive and illuminating Introduction to this one-volume collection, Alfred Rubin pays tribute to his former colleague and points to a number of the most impressive features of the Gross essays. In discussing the criteria of his choice, he concludes: `Tough choices had to be made to present the reader with the widest and deepest selection of the works of a wide and deep mind. The bottom line was always the utility of the selection to the next generation of students of public international law and organization. '

This focused collection of essays on various aspects of the law of treaties does justice to its honoree, scholar and author Professor Bert E.W. Vierdag, on the occasion of his retirement as Professor of International Law and International Relations at the University of Amsterdam. Written by leading academics in the field as well as practitioners and former practitioners, the essays cover: - the alignment of treaties with more general sources doctrine, addressing such issues as conflicts between various types of treaties and the relationship between treaties and customary international law, and between treaties and domestic law; - the emergence of treaty norms through various ways and methods; and - the creation of treaty law in several branches of international law. This cohesive, focused, expert work will assist and appeal to both academics in the fields of public law and political science and professionals engaged in international negotiations and treaty-making.
