'This book promises to be an important scholarly contribution to the social analysis of technology. I would recommend the book to anyone wishing to understand the evolution of a technology, and especially how the relations between designers and users play a role in that shaping process.' - Neil Pollock, University of Edinburgh, UK'This groundbreaking work traces the complex relationship between designers, developers and users in the biography of technical artifacts – anyone interested in the nature and process of technical innovation will find much to meditate on and much to apply.'
