This book has its origins in a five-part seminar series, Transplantation and the Organ Deficit in the UK: Pragmatic Solutions to Ethical Controversy, which was funded by the UK Economic and Social Research Council (ESRC) between 2006 and 2008 (RES-451-25-4341), and we gratefully acknowledge its support. The seminar series brought together a multi- disciplinary and international group of ethicists, lawyers, clinicians, scientists, sociologists and patient advocates who all had interests and expertise in the field of organ donation and transplantation.
