Written by a sociologist and a biologist and science historian, this text considers the social aspects of organ transplantation and chronic hemodialysis. Their research, begun in 1968, focused on the experience of research physicians engaged in this work, the "gift- exchange" social dimensions of these practices, and the impact of these technologies on society as a whole. This reprint of the 1978 edition includes a new introduction by the authors. c. Book News Inc.
