Perhaps you should try some spelling variations:
grandi libri » amandi libri, grandi liberali, gran libro
magni libri » amandi libri
libri nel » libri del, libri ne, libri nella
i grandi » i grand, e grandi, i grani
i magni » i magna, i magi

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 magni libri nel((la litterature) OR (a literature)) di ) OR ( i grandi libri ((la litterature) OR (a literature)) arti ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i magni libri nel((la litterature) OR (a literature)) di ) or ( i grandi libri ((la litterature) OR (a literature)) arti ))*".
