Perhaps you should try some spelling variations:
della letteratura » nella letteratura, e letteratura
alla letteratura » nella letteratura, la letteratura, tra letteratura
literatura arte » literatura artes, letteratura arte, literature arts
y literatura » la literatura
i grund » i grunde, i ground, i grand
libri y » libri v, libri x, libri e
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 grund libri y literatura arte ) OR ( i gran libro ((alla letteratura) OR (della letteratura)) storia )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grund libri y literatura arte ) or ( i gran libro ((alla letteratura) OR (della letteratura)) storia ))".
• Adding a wildcard symbol may retrieve word variants: (( i grund libri y literatura arte ) or ( i gran libro ((alla letteratura) OR (della letteratura)) storia ))*.
