literatura arte » literatura artes, letteratura arte, literature arts
de litterature » la litterature, et litterature
y literatura » la literatura
grandi libro » gran libro, grand livre, grande livre
1 magni » 1 maggio
libri y » libri v, libri x, libri e

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: (( 1 magni libri y literatura arte ) OR ( i ((grandi libro) OR (amandi libri)) de litterature sarda )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 1 magni libri y literatura arte ) or ( i ((grandi libro) OR (amandi libri)) de litterature sarda ))".
• Adding a wildcard symbol may retrieve word variants: (( 1 magni libri y literatura arte ) or ( i ((grandi libro) OR (amandi libri)) de litterature sarda ))*.
