Review of the hardback: 'It is such a pleasure to read this book. It is sensual and sleek, beautifully printed on the finest paper, comprehensively (and not over abundantly) illustrated, and written, with clarity and verve … It has many fine-screen half-tones, beautifully photographed documents, fine colour pictures and the page design is impeccable … Cambridge University Press and the authors deserve high praise for a thorough and diligent job well done.'
