... a wonderful book! ... a comprehensive treatment of the fauna, flora and formations of the last 2 million years... every serious library must have a copy. ' Journal of Coastal Research, 1: 4 (1985) ... an amazing book, in part because it has often been said in recent years that no single author these days could put together such a synthesis... an easy-to-read, well-written, amazingly thorough treatise on the Pleistocene. It is without equal among the current monographic works in terms of coverage, depth, and timeliness... Nilsson has captured the flavor of the history, development, and controversy of Quaternary science and provided us with an invaluable source book. ' Arctic and Alpine Research, 17: 3
