Thanks to the hard work of our colleagues from the easteurotopo.org we have added new Russian and Soviet 1:84,000 maps, so-called "2-verst map", courtesy of the Library of Congress. 231 new sheets provides more thorough coverage of, Latvia, Lithuania, Poland and Ukraine.
We do not expect to receive more sheets of this map type by end of summer 2015, but we should be able to add other Russian maps, of various scale.

Courtesy of the Earth Museum in Warsaw, Poland, we have added about 100 sheets from a map collection called Geological Atlas of Galicia (Atlas Geologiczny Galicji), which were produced between 1880s and early 1900. Index sheets presenting the stages of this long-term project can be found at the bottom of the map list. The maps are based on the Austrian 1:75,000 "Spezialkarte". There are approx. 30 sheets still missing, but over the next few weeks we should be able to add most of them from other sources.

We have received, from the collection of the Uniwersity of Illinois Library several sheets of a rare, German 1:50,000 map (Deutsche Karte), covering, in a crescent shape, some areas of western Poland. All sheets have been scanned at 400 dpi resolution. Please note, that while we have received a permission to use the scans for non-commercial purposes on the Internet, the university imposes certain restriction, i.e. licencing fees on some use of the materials, e.g. in publications. The list of these fees is available in the pdf document and can also be found in the each file's "datasheet" on Mapster.

Courtesy of Pracownia Zbiorów Kartograficznych i Reprografii Cyfrowej Wydziału Nauk o Ziemi of the Nicolaus Copernicus University, Torun we have been able to add some 170 sheets of the WIG 1:25,000 maps. Most of the new sheets are Polish, pre-WW2 editions, several others are German, WW2 reprints and variants. There are also a few older, Polish editions from mid-1920s, based on earlier, pre-WW1 German 1:25,000 Topographische Karte (Messtischblatt) editions.

We would like to introduce, with some delay, new maps:
- from cartographic collections in New Zealand, 42 sheets of W.I.G. 1:100,000 tactical map, 600 dpi. They are black-and-white reproductions of original maps evacuated from Poland to the West in September 1939. Reproductions were issued in 1942 by the Wojskowy Instytut Geograficzny based, by that time, in Edinburg.
This edition is nearly identical to the original, pre-WW2 edition, although different reproduction technology was used, and some older sheets, originally from 1920s, were given WIG grid lines. It is worth paying attention to the original publication dated at the centre of the bottom margin as, in some cases, reproductions are based on later editions than the maps available in our main index sheet.
- courtesy of biblioteki Wells Library Map Collections, Indiana University, some 750 sheets of a 1:50,000 Soviet map (600 dpi) have been added. The sheets partly coincide with the earlier scans obtained from the German University of Greifswald, but quite a large number of sheets complement the coverage.
- courtesy of The Library of Congress, with help from our partners at easteurotopo.org, we have received a new batch of 3-verst maps, of which a majority are Russian and Soviet originals, and the rest are German reproductions from WW1.
- several new town plans from the Library of Congress, mainly covering European part of Russia, including some post-WW2, town plans of Moscow, Leningrad, Odessa, possibly produced by the CIA, and one, interesting war-time, German plan of a Ukrainian city of Stalino, currently well-known under a different name of Donetsk.

We have added some 160 town plans from the digital library of the University of Wroclaw. Unfortunately, as most digital libraries do not provide direct access to scanned material (jpg), instead embaring on a convoluted on-line viewing options (java, zoomify, etc), we are unable to determine the resolution of scanned images, consequently this information is not available in the file metadata, displaying, instead, resolution of 75 dpi or 96 dpi. We have been informed that they were scanned in a range of resolutions ranging from 300 to 600 dpi.
The easiest way to find out which plans are new, is to visit the lists, rather than index sheets of Mapster, as all new material is labelled accordingly (in green):

• Town plans – Central Europe

• Germany

• Others

• 64 sheets of the WIG 1:300 000 "operational map". Some of the new scans replace those previously scanned at lower resolution (300 dpi), others are new editions of the sheets already available, and some are of completely new areas,

• 16 Polish and 4 German copies of 1:25,000 W.IG. "detailed map", including one covering Janowa Dolina.

• 7 sheets of the older W.I.G. 1:25,000 maps, from mid-1920s, including six, very rare sheets from the "Rejon Bydgoszcz” and one (last missing sheet) from the Rejon Brześć.

Over 70 new Russian and Soviet maps have been added from the map collection of Geography Department of the Humboldt-Universität zu Berlin. There are some 40 sheets of the one-verst map (1:42,000) and several sheets of the two-verst map (1:84,000), as well as several sheets of the Soviet 1:25,000 map. Please note that while the dating is accurate, it refers to the date of print, but the map can display information and situation several dozens years prior to that date! This refers, in particular, to the one-verst sheets covering the (then) Polish eastern borderlands (Kresy), which  are based on Tsarist survey data, Polish 1:100,000 maps by W.I.G. and intelligence reports, rather than, for obvious reasons, the latest field survey information.

Courtesy of the Geography Department of the Humboldt-Universität zu Berlin we have been able to fill in some gaps in the map coverage:
- approx. 70 sheets of the German 1:300,000 map (Ãœbersichtskarte von Mitteleuropa) covering the area from France to Kazakhstan.
- several sheets of the German 1:800,000 map and Austro-Hungarian 1:750,000 map
- a few maps from a very rare German series "Deutsche Karte", in 1:50,000 scale: 3 small sheets from 1920s and 5 large-format sheets from 1938.

From the collection of the Library of Congress: a few sheets of a very rare Austro-Hungarian 1:25,000 maps covering extensive fortifications of Brest-Litowsk and surrounding area, and one sheet from a similar series covering the fortifications of Luck, Dubno and Rowno. As the set is currenctly incomplete, we will attempt to acquire the reminder from Austrian sources.

From the collection of a digital library of the University of Wroclaw, Poland some 450 shets of a German 1:25,000 map (Messtischblatt) covering Śląsk (see sheets on list beginning with No 3957 Rädnitz).

A few years ago, courtesy of the Library of the Brigham Young University, Utah, we were able to add several hundred post-WW2 American copies of German Messtischblatt sheets covering East Prussia and, generally, western Poland. We have finally made use of the other, substantial part of the collection. It consists of American, British and French editions of the 1:25,000 map from the territory of present-day Germany. All in all 2550 some 2550 sheets (400 dpi) and some 50 more sheets from our collection (600 dpi).

Other new maps:
- some 100 sheets of the Czechoslovak 1:200,000 map, dated 1919 - 1939
- over 50 German 1:100,000 maps (Karte des deutschen Reiches) dated 1920 - 1942
- an interesting map dated approx. 1941 - 1942, with a rather self-explanatory title: "Kreuzung der Autobahnen Breslau – Moskau und Danzig bei Litzmannstadt”

Further updates can be expected - next year.
