18 sheets of WIG 1:100,000 maps have been added. They include older variants, from 1920s, from the area of Kresy, and newer editions. from 1930. All sheets available in 300 dpi and 600 dpi. New maps have been marked with a green "New" bubble on the lists.
We have also added approx. 30 scans (600 dpi), to the collection of German air photo maps (Bildplan edition) courtesy of archiwum Wydziału Geologii i Geografii UAM in Poznan, Poland. Majority of those sheets have already been made available in 400 dpi, but this wasn't good enough, so all will have been re-scanned at 600 dpi. We expect around 170 – 180 sheets (in total) from the same source, but please bear with us, as scanning might take some time, perhaps another 2 - 3 months.
Courtesy of the University of Chicago Library we are able to show 230 scans of the Red Army General Staff maps of Eastern Poland, dated 1939, scale 1:25,000. The maps cover the area of Polish Wołyn (Volhynia) and they were produced, probably, in preparation of the "liberation" of the area in late 1939. The maps are a slight re-scale job of the tsarist, topography survey sheets, so-called half-verst maps (1:21,000), with no evidence of updating. Therefore, it should be assumed they are accurate as per the date shown in the top-left corner, i.e. approx. 1885 – 1905. These maps are rather important, as, in many cases, they are the only detailed map of a given area until, at least 1940.
We don't know the total number of sheets produced in this "block", there could be, up to 600 sheets printed in 1939. Another set of scans, around 100 strong, could become available in the next 2 months.
