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.
