Written by one of the world's leading academics in the field of the law of international organizations, this book provides what it claims to offer. It is an introduction as it gives in a nutshell an easy-to-read general overview. It is advanced in the sense that it is written on the basis of profound knowledge of the field, and it has an excellent bibliography for those who want more. Like Rembrandt in his later works, Jan Klabbers is painting with broad strokes, in his own style, providing those who are not experts in the field a modern framework for better understanding international organizations and their law.'
- Niels Blokker, Leiden University, the Netherlands'International organizations are a major factor in world affairs and in all areas of human collaboration. This book is a valuable resource next to existing textbooks and treatises on international institutional law. It offers a concise and engaging account of the role of international organisations and, in clear language, sets out what is the legal framework for their manifold activities and political operations. Great reading, and the essential introduction to international organisations as political and legal actors in the world today.'
- Catherine Brölmann, University of Amsterdam, the Netherlands
