The format of Delson's encyclopedia makes it useful for ready reference. Highly recommended for all academic and large public libraries." -- Choice"Top-notch background source for students, professionals and the informed general reader. More substantial than the Cambridge Encyclopedia of Human Evolution and with a more useful alphabetical arrangement, this reference will be of particular interest to academic and larger public libraries." -- Against the Grain"This is a very readable, thorough reference source covering every aspect of human evolution and prehistory...This encyclopedia continues to be the most inclusive and authoritative source of information on anthropology and human evolution. It is an essential source for all academic libraries and large public libraries." -- Booklist/RBB"Although a second edition, this constitutes overall a new book, rich in figures maps and scaled drawings, much fuller, more comprehensive and diverse than its forerunner. ...no institution, regardless of size can afford to forgo having a copy available for its membership and clientele. It constitutes a singularly effective and representative resource of the scope and state of understanding of human biological and behavioral evolution." -- Journal of Human Evolution
