The American legal system is the most significant in the world today, yet until the publication of Fundamentals of American Law there has been no book that provides both the basic rules and the theoretical understanding necessary to comprehend it. This book is not simply the work of a single author, but a collection of especially written essays, done by experts in their fields, all of whom are on the faculty of New York University School of Law, which is recognized as one of the elite law school in America and which offers this book as an element of its unique Global Law School Programme. One of the main advantages to teachers of American Law is that we will be offering a Teacher's Manual to anyone who asks for the book on inspection.
