My military history of the 1964 coup d'état is a couple months away, Kohlzine should be proud as it'll have a lot of historical information that has never before been compiled in the English language. There are a few things to consider about how to fit the text. It'll be quite long and I can see difficulties with the images. Besides photographs it'll have orders of battle and maps. Not only will they add up space but there are two concerns about the maps:
1) Color. It's a nice challenge to fit them all to a B&W scheme but usually I'd employ more than two colors to distinguish between allegiances of military units.
2) Size. Most/all will be wider than they are tall and I want to make use of a page's full space. Physically this is normally done by flipping the map to the side, filling the page, and the reader turns it around himself; this is how it'd work in the printable version. But for the .pdf it might be more convenient to have the page itself turned to the side.
