I put in a review request for Philip Laino's new edition of Gettysburg Campaign Atlas (2015) a while ago and it slipped my mind as I never heard back from the publisher. It deserves belated mention as the GB world seems to swear by Laino's work. "The much anticipated 2015 revised and expanded edition of the Gettysburg Campaign Atlas. The revised Atlas has 510 pages containing 444 maps" and covers "the march to Gettysburg, July 1st, July 2nd, July 3rd and the retreat and pursuit." One rarely prefers books being spiral bound but in this case it might help use in the field.
On another Gettysburg front, I predicted that Gettysburg, July 2: The Ebb and Flow of Battle (2013) by James A. "not the actor" Woods would sell out quickly and become a collector's item. Looks like there are still copies left for the stragglers.
