Members of this forum are probably familiar with the Russian-German project to digitize WWI German documents in the archives of the Russian Federation. The webpage is here: http://www.germandocsinrussia.org/en/nodes/1-russisch-deutsches-projekt-zur-digitalisierung-deutscher-dokumente-in-den-archiven-der-russischen-foderation
As part of my research, I downloaded all the German General Staff maps from the webpage that show the location of French, British and Belgian forces on the Western Front from Feb 1916 to Nov 1918. The maps are a great resource, but frankly, downloading 112 maps one-by-one and organizing them by date was maddening. But I did it, and will gladly send the entire collection via the ftp site www.wetransfer.com to anyone who wants the collection. Each map is approximately 2 to 3 MB and the entire collection is 304 MB.
I have attached a low-resolution copy of one of the maps.
It is a neat collection. I need your email address for the ftp site. Please PM me or use the contact form on my webpage - http://www.digitalhistoryarchive.com/contact-us.html
