Perhaps you should try some spelling variations:
sudostdeutschen historische » sudostdeutschen historischen (Expand Search)
historische kommission » historischen kommission (Expand Search)
der sudostdeutschen » des sudostdeutschen (Expand Search)
band 12 » band 2 (Expand Search), band 1 (Expand Search)
band 11 » band 1 (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "buchreihe der sudostdeutschen historische kommission, ((band 12) OR (band 11))~".
• Adding a wildcard symbol may retrieve word variants: buchreihe der sudostdeutschen historische kommission, ((band 12) OR (band 11))*.
