Perhaps you should try some spelling variations:
historischen kollegs » historischen rolle, historischen kontext, historischen fallen
historischer kollaps » historischer atlas, historischer vorlauf, historischer kontext
anschriften der » schriften des, vorschriften des
schriften der » schriften des, schriften uber, schriften zur
kolloquium » colloquium

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((schriften der) OR (anschriften der)) historischen kollegs : kolloquien ) OR ( ((schriften der) OR (anschriften der)) historischer kollaps : kolloquium )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((schriften der) OR (anschriften der)) historischen kollegs : kolloquien ) or ( ((schriften der) OR (anschriften der)) historischer kollaps : kolloquium ))".
• Adding a wildcard symbol may retrieve word variants: (( ((schriften der) OR (anschriften der)) historischen kollegs : kolloquien ) or ( ((schriften der) OR (anschriften der)) historischer kollaps : kolloquium ))*.
