Perhaps you should try some spelling variations:
e letteratura » y literatura
ii literatur » vi literatur, viii literatur
literatur de » literatur die, literatur der, literatur des
grunde des » grund des, grunde der, grundzuge des
livre ii » livres ii, livre iii, livre i

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: (( i grunde des ((e letteratura) OR (e literatur)) sarda ) OR ( i grand livre ii literatur de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grunde des ((e letteratura) OR (e literatur)) sarda ) or ( i grand livre ii literatur de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grunde des ((e letteratura) OR (e literatur)) sarda ) or ( i grand livre ii literatur de ))*.
