This useful source on the westward expansion consists of eight essays by various authors: Mapping the Trans-Mississippi West: Annotated Selections; The Notorious Doctor Robinson; A Tale of Two Cartographers: Emory, Warren and Their Maps of the Trans-Mississippi West; Exploration and Mapping of the Southwest Route, from Missouri to Southern California; The Wagon Road Surveys; George M. Wheeler and the Geographical Surveys West of the 100th Meridian, 1869-1879; Mapping the United States-Mexico Borderlands: An Overview; Mapping the Southwest: A Twentieth Century Historical Geographic Perspective. There are 28 well-chosen monochrome illustrations.  The first essay is particularly useful to collectors of Americana, since it gives information on the significance of 29 important maps showing North America from 1540 to 1848, most of -which can be found on the market.  The later essays are more specialized, but equally useful within their scope.  This book is recommended for Americana collectors and dealers.
