East German Duden (Leipzig)[edit] The first East German Duden appeared in Leipzig in 1951 but was largely ignored as illegitimate by West Germany. Of note, there are a few semantic changes recorded in the East German Duden that evolved from contact with Russian. The few lexical and semantic items recorded in the East German Duden migrated from Der große Duden because the printing press in Leipzig did not publish the multiple volume Duden which has become the current standard.
