I've written about the Savas Beatie Military Atlas Series before. I recently read the next three published books,

v6 The Maps of the Wilderness (2016) [+]
v7 The Maps of Fredericksburg (2018) [+]
v8 The Maps of the Cavalry in the Gettysburg Campaign (2020) [/]

All by Bradley M Gottfried. Wilderness was interesting because I knew little about it and it was basically a 2-day battle. The maps are very good at identifying units even though it was a very confusing battle to those involved. Fredericksburg gives a good account of how piecemeal the attacks were and again the maps are quite helpful.

Cavalry in the Gettysburg Campaign the maps were ok. I think because less and smaller units and lots of skirmishes the detail is often lacking. Still, there is a nice account of Buford's defense at the first day of Gettysburg.

Writing is good enough. Fairly clear and detailing what's going on with some asides but not intended to be scholarly work sans the maps.

Hardcover books with colors maps and quality paper. Definitely still a worthwhile series to continue collecting
