The author has produced a long-needed and very useful index to animal and plant illustrations. Following the same format as two earlier indexes, John W. Thompson and Nedra G. Slauson's Index to Illustrations of the Natural World ( LJ 8/15/77) and Lucille T. Munz and Slauson's Index to Illustrations of Living Things Outside of North America ( LJ 9/15/81), Clewis concentrates on books published in the 1980s and includes organisms from around the world. This book contains approximately 6200 entries referencing 142 books. Illustrations can be accessed by either common or scientific name. A comprehensive and useful reference source, it is recommended for most public and academic collections.--Mary J. Nickum, Fish and Wildlife Reference Svce., Bethesda, Md.
