Yikes, Timon, who would have thought? They write outside my area of interest so I had never heard of them before. Very clever of them and I certainly wish them the best of luck. I did 90% of my Luftwaffe research in Washington, AFHRA at Maxwell AFB, USAMHI Carlisle, BNA London, BA-MA Freiburg, Zagreb, Ljubljana, and U.S. university research libraries up and down the East Coast, but all before 1998 when the age of the PC arrived. We had to pay for everything ourselves back then. And now it's possible to get others to pay for it.
