Very many thanks to Jennifer Jenkins, my partner, who has read this book and made wonderfully helpful suggestions that have prompted amendments.
The book started with an invitation from Silvia Langford of Elwin Street. Among others who made suggestions at that stage were Mark Frary, Pippa Crane, Jeremy Stangroom, and Oliver Salzmann. Next, I took over management of the book myself, and Princeton University Press took it on. During this phase, Oliver Salzmann continued to be helpful. I am grateful to the book’s editor, Sarah Caro; to her assistant editor, Hannah Paul, of Princeton University Press in Oxford, UK; to Sara Lerner, the book’s production editor in Princeton; to Karen Verde, of Green Pelican Editorial Services, who copyedited the manuscript; to two helpful anonymous reviewers; and to my literary agent, Andrew Gordon. I thank, as well, the many others who have taught me, influenced me, and enabled me to think and write about the issues of this book.
