Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
ii literatura » ii literatur, ii literature, iii literature
i literatura » y literatura, i literature, a literatura
grand libro » gran libro, grand livre
libri de » libro de, libri duo, libri sex
libre de » libro de
i grund » i grunde, i ground
i grand » i grunde

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 grund ((libri de) OR (libre de)) letteratura sarda ) OR ( i grand libro ((i literatura) OR (ii literatura)) de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund ((libri de) OR (libre de)) letteratura sarda ) or ( i grand libro ((i literatura) or (ii literatura)) de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grund ((libri de) OR (libre de)) letteratura sarda ) or ( i grand libro ((i literatura) or (ii literatura)) de ))*.
