1. Birch Coulie: The Epic Battle of the Dakota War by John Christgau (Bison Books, 2012).
With irregular citation, no bibliography, and no maps or illustrations of any kind, first impressions do not impress. I expect more from Nebraska's Bison imprint, but it may turn out okay.
2. Historical Atlas of Oklahoma by Charles Robert Goins & Danney Goble, maps by James H. Anderson (Univ of Okla Pr, 2012).
This new paperback reissue of the 2006 4th edition has just been released.
