1. The Illustrated Gettysburg Reader: An Eyewitness History of the Civil War's Greatest Battle by Rod Gragg (Regnery History, 2013).
An illustrated (w/ maps, photos, prints, sketches, etc.) collection of Gettysburg first person accounts.
2. The Gettysburg Campaign in Numbers and Losses: Synopses, Orders of Battle, Strengths, Casualties, and Maps, June 9 - July 14, 1863 by J. David Petruzzi and Steven Stanley (Savas Beatie, 2013).
I love books like this. I don't know how commercial they are, but it would nice if this could be the beginning of a series similar to the S-B campaign atlases.
