We are grateful to the authors for their willingness to write chapters in the spirit of this book. Their cooperation has greatly enhanced the cohesion and clarity of the proj ect. We also thank the British Acad emy for its enthusiasm in hosting a series of workshops in 2018 and 2019 on new urban grammars, from which this book germinated, and for facilitating its open access. Philip Lewis and Desislava Stoichkova created the opportunity and believed in the need to open new ways of "thinking the urban." We are also indebted to Courtney Berger at Duke University Press for her support and encouragement, to Chen Qu for invaluable help in tying together references and biblio graphies, and to the two referees who offered valuable suggestions to strengthen the manuscript.
