NPS bibliography - "The Civil War in the American West"

Gordon Chappell of the National Park Service has compiled a good, up-to-date for the Sesquicentennial bibliography of the Civil War in the regions comprised of the "Far West, the Southwest, the Pacific Coast, the Pacific Northwest, the Rocky Mountain territories, and the Great Plains from Minnesota and North Dakota to Texas". It is definitely worth a look, both for the list and the brief commentary. I've read most of the books on it (which means I'm crazy or the available literature is limited or both) but learned of many more that are now on my to-do list. Many thanks to Mr. Chappell.
