Perhaps you should try some spelling variations:
letteratura sarda » letteratura storia, letteratura sulla, letteratura arte
ii literatura » ii literatur, ii literature, iii literature
literatura de » literatura y, literatura en
grand libro » gran libro, grand livre
i ground » i group, i groups, i grunde
libri ii » libri iii, libri iv, libri xv
libro ii » libro vii, libro di, libro i
i grand » i grunde

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 ground ((libri ii) OR (libri v)) letteratura sarda ) OR ( i grand libro ii literatura de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i ground ((libri ii) OR (libri v)) letteratura sarda ) or ( i grand libro ii literatura de ))".
• Adding a wildcard symbol may retrieve word variants: (( i ground ((libri ii) OR (libri v)) letteratura sarda ) or ( i grand libro ii literatura de ))*.
