Ezra Padoa writes with a few links to collections of Russian/Soviet maps. First off are collections of Soviet military topographical maps. Says Ezra, “I’ve heard that Soviet military cartographers could be tried for treason if they made any mistakes. At this site you can find many fruits of that evil genius.” And at that site (which is a general digital topographical map archive, containing maps from several sources, not just Soviet) there’s a link to this site, which has even more Soviet topo maps.

In a related vein, Ezra also shares a link to Old Maps of Russian Asia — early 20th-century maps of central Asia.
