Perhaps you should try some spelling variations:
litterature author » literature author, literature authors, literature anthony
de litterature » la litterature, et litterature
de letteratura » e letteratura, di letteratura, de literatura
de litteratura » de literatura, e letteratura, da literatura
grand liberte » grande liberte, grand livre
i grand » i grunde
i gran » i grain, i grani, i gram

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 gran libro de litterature author ) OR ( i grand liberte ((de letteratura) OR (de litteratura)) arte ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i gran libro de litterature author ) or ( i grand liberte ((de letteratura) OR (de litteratura)) arte ))*".
