This volume provides a comprehensive and up-to-date survey of public international law, with useful references throughout to classic and contemporary cases and scholarship. It is designed as a stand-alone text or as a complement to any of the major casebooks on the topic. The first section of the book addresses the fundamental history and structure of international law; the second section focuses on the interface of international law and national law; and the final section presents the treaties and rules that comprise the major fields of international law: human rights, law of the sea, international environmental law, and more.
