'Spolsky and Cooper weave a rich brocade ... this is a well written and engaging book. The historical chapters are richly written; the reports of modern studies are serviceably written without overreliance on jargon. The book is carefully produced ... the authors have skillfully woven together the numerous interesting themes they have chosen into a handsome volume that I highly recommend.'Loraine K.
