Perhaps you should try some spelling variations:
das schrifttum » des schrifttums (Expand Search)
schrifttum des » schrifttum der (Expand Search), schrifttums der (Expand Search), schrifttum heft (Expand Search)
forderung das » forderung des (Expand Search), forderungs des (Expand Search), forderung der (Expand Search)
des deutschen » der deutschen (Expand Search), die deutschen (Expand Search)
band 4 » band 2 (Expand Search), band i (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: "forderung das schrifttum des deutschen aus bessarabien : ((band 4) OR (band 1))~".
• Adding a wildcard symbol may retrieve word variants: forderung das schrifttum des deutschen aus bessarabien : ((band 4) OR (band 1))*.
