This book comprises the collected and revised papers from a conference on comparative British and American contract law, held at the University of Edinburgh Law School in September 2013. The topics selected for the conference, and hence for the chapters of this book, were intended, in ranging across the spectrum of contract law, to illuminate the extent to which similarities and differences exist between the laws of both countries. In comparing the common law of contract of the United States and the United Kingdom (specifically England and Scotland), the authors have undertaken valuable doctrinal, as well as some theoretical, work in a neglected field of comparative law. As editors of this work, it has been our pleasure to work with leading contract scholars from both sides of the Atlantic. We also had the privilege of hearing at the Edinburgh Conference from Lord Hodge, Justice of the Supreme Court of the United Kingdom, and subsequently of including his keynote address within this collection. We are very much in the debt of all of the contributors to this volume, from whom we have learned and who have enriched, and will continue to enrich, this quintessential area of private law. We are also indebted to the University of Edinburgh for its support, both financial and administrative, in relation to the holding of the conference, out of which the contributions to this volume were born. In particular, much of the administration of the conference was ably undertaken by Simon Kershaw of the University of Edinburgh, to whom we extend our grateful thanks. Our thanks are also due to the University of Florida, Warrington College of Business Administration, for financial support for the conference. We have been ably assisted in our work by the commissioning and editorial staff of Oxford University Press, who had faith in the value of this project, and who have been on hand to advise and help us as the book progressed from idea to finished work.
