----------------------------Original message---------------------------- Does anyone out there own the set "Karte von Berlin 1:4000"? It was published by Institut fur Angewandte Geodasie. Sheets in our set date from 1964 to 1977. Our set is incomplete and we lack one needed by a patron. Our set does not have an index so we would like to locate one to help identify the pertinent sheet. If you own this set and are willing to help please reply directly to me. Thanks, Pat Scott Map Collection Penn State University [log in to unmask] (814) 863-0094
