Query: A concise, but quite complete overview on WW2

I own the original italian edition of this book; it's a quite complete listing of every fact, every battle or political event of some importance. The most important event (such as Normandy landing, the Bismarck hunting and so on) are "exploded" in dedicated pages at a lower, more detailed, level. There are a lot of photos and maps that help to understand the course of the events. If I should find a fault it could be this one: naval aspect are covered only as regard the main events and battles, but the most of everyday battles are not dealt with. So if you are interested mainly in the naval war you should search for another reference book. Apart from this, Salmaggi's work is a useful reference, a worthwhile book
