1. Railroads of the Civil War: An Illustrated History by Michael Leavy (Westholme, 2010).
The text portion of the book is a pretty general overview (not a scholarly look at the war's use of railroads or their equipment), but the pictorial facet is the main focus and there are loads of photographs I [admittedly, not a railroad guy] have never seen before in print.
2. Shadow of Shiloh: Major General Lew Wallace in the Civil War by Gail Stephens (Indiana HS Pr, 2010).
This attractive oversize volume has the appearance of a well researched and documented examination of Wallace's command history in western Virginia, Kentucky, Tennessee, and Maryland. I look forward to reading what, if anything, it can add to our current understanding of the Shiloh controversy.
