Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, duale studien
de literatuur » de literatura, en literatuur, de litterature
de literatur » de literatura, de litterature, erde literatur
bast scale » best scale, vast scale, basin scale

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: "bast scale studien _ filosofia ((de literatur) OR (de literatuur))".
• Adding a wildcard symbol may retrieve word variants: bast scale studien _ filosofia ((de literatur) OR (de literatuur))*.
