Two of the TSHA's most enduring titles examine how the land has been perceived and drawn by mapmakers. The beautiful revised Maps of Texas and the Southwest, 1513-1900, by James C. Martin and Robert Sidney Martin, features more than sixty-five maps, seventeen in full color. Contours of Discovery, by the same authors, is a handsome collection of twenty-two historic maps, eighteen in a large, full-color format designed for display or framing. A sixty-six-page illustrated guide accompanies the collection of maps.
