THE MAPS OF CANADA N. L. Nicholson and L. M. Sebert. Hamden (CT), Archon Books, c1981. Distributed by Archon Books, 995 Sherman Ave., Hamden, CT, 06514, USA. 251pp, cloth, $32.50. ISBN 0-208-01782-8. Grades 11 and up. Reviewed by Robin Lewis. Volume 11 Number 1. 1983 January. A comprehensive survey of systematic government mapping is given in this book. The distinctive changes in each edition of topographic map or atlas are explained. The formation of the civilian, military, and geological mapping establishments is related to the types of maps produced. As we read, we see the production of maps respond to new user requirements, and we gain respect for the workers who have struggled to complete standardized surveys of our vast, sparsely-settled country. Federal hydrographic charts and provincial thematic maps are described briefly. Short sections discuss projections, reference systems, map accuracy, and geographical names. The book contains a useful index and helpful subheadings. Notes and references and a token glossary are included. Appropriate black-and-white illustrations are used. The research has been exhaustive, and the attention to detail is meticulous. The subject is technical at times, but explanations are as clear and precise as a good map. This book will be enthusiastically received by cartography students, geographers, and map buffs. Sebert, formerly of the Topographic Survey of Canada, wrote the popular booklet Every Square Inch. Nicholson, chairman of the department of geography at the University of Western Ontario, is known for his text The Boundaries of Canada. Their expertise has produced a knowledgeable account of official Canadian mapping. Robin Lewis, Riverdale HS, Montreal, QB.
