Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
de letteratura » e letteratura, di letteratura, de litteratura
literatur ai » literatur a, literatur a1, literatur am
iv gran » iv grand, iv grain, iv gram
libro e » libero e, libro i, libro _
i grani » i grandi, i grand, dei grani

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: "(( iv gran libro e literatur ai ) OR ( i grani libro de letteratura sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( iv gran libro e literatur ai ) OR ( i grani libro de letteratura sarda ))*.
