Jukka, they have been reprinted by Whitman Publishing in hardcover, excellent binding, and with the foldout maps in the back folder......I own all of them, but buy them new, not used, because sometimes if they're used the maps are not there anymore. Make sure to get the Whitman Publishing ones.

Unfortunately, the Mediterranean Theater of Operations books have only been reprinted in cheap paperback versions without the folder of maps. For those I bought the original "Green Backs." They are all excellent books. These you might have to buy used because they can be pricey, but make sure the seller has ALL the maps from the back folder.
I also highly recommend the British official histories as well as the Canadians. I especially like the Canadians history in Italy. Another thing I like about the U.S. British and Canadians histories is even though they are from the Allies perspective, they go into a lot of detail, tactically and operationally from the German perspective as well. They have quite a lot of detail on German units, down to battalion level at times, and commanders. That is why I bought them.
And the maps are the best! Too bad Germany doesn't have a really good detailed Military history, in the same vein as these ones from the Allies. Their "official" history "Germany and the Second World War" is more of a sociological and economic "grand strategy" type of series. For military matters it is nowhere as detailed as the U.S. British and Canadians histories. The only exception would be VIII by Frieser which is really good.
