Perhaps you should try some spelling variations:
de litteratura » de litterature, e letteratura, da literatura
literatura del » literatura de, literatura el, letteratura del
de literatura » de litterature, la literatura, y literatura
e literatura » y literatura, e literatur, a literatura
i grundei » i grunde, i grund
libro e » libro de, libero e, libro i
i gran » i grand, i grain, i grani

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 grundei libri ((de litteratura) OR (de literatura)) sarda ) OR ( i gran libro e literatura del )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grundei libri ((de litteratura) OR (de literatura)) sarda ) or ( i gran libro e literatura del ))".
• Adding a wildcard symbol may retrieve word variants: (( i grundei libri ((de litteratura) OR (de literatura)) sarda ) or ( i gran libro e literatura del ))*.
