The editors wish to express their thanks to the Arts and Humanities Research Council for generously funding the three-year ‘Preventive Justice’ Project (AHRC Project Number AH/H015655/1) from which this volume arose. We also thank Dr Ambrose Lee, Post-Doctoral Research Officer on the project for his excellent research and organizational help; Gabrielle Watson for her superb editorial assistance; and Alex Flach, Natasha Flemming, and colleagues at OUP for seeing this volume through to production. We are grateful to all those who participated in the two Preventive Justice seminars held at All Souls College, Oxford in September 2011 and January 2012. Particular thanks go to those who acted as formal respondents to the papers upon which these chapters were based: James Edwards, Cécile Fabre, Andreas von Hirsch, Murray Hunt, Nicola Lacey, Ian Loader, Laurence Lustgarten, and Shlomit Wallerstein. Last but certainly not least, we thank all the authors whose chapters appear here for devoting their very considerable acumen and insight to the questions of preventive justice that we posed to them and, in so doing, helping to further the aims of our Preventive Justice Project.
