Donna P. Koepp, ed. Exploration and Mapping of the American West: Selected Essays.
Chicago, 1986. Cloth. Out of Print.
A useful source on the westward expansion, the volume consists of eight essays by various authors. The first essay, Mapping the Trans-Mississippi West: Annotated Selections, 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.
