Hello All, We are organizing our set of the *Deutsche Grundkarte 1:5000* map series (see a great explanation of the set in this blog story <https://specialcollections-blog.lib.cam.ac.uk/?p=17788> from Cambridge University Library). One issue is that we do not have an index for the maps -- does anyone happen to have an index map? If yes, would you be willing to send us a scan of it? We would be very grateful!
