Up to 50 sheets of Russian 3-verst map (1:126,000) have been added, courtesy of the digital library of the Jagiellonian University, Krakow, and the Library of Congress. Also, after some painstaking effort, it hs been possible to make those maps, as well as the WW1 German variants, available through index sheets; consequently, these maps are now easily available through Mapster place-name search engine.
Several other index sheets have been created, including a mid-19th century Polish "Mapa Kwatermistrzostwa” (1:126,000) from the digital archive of the National Library, Warsaw.
