Perhaps you should try some spelling variations:
litterature arte » literature arts, literature art, letteratura arte
iv letteratura » e letteratura, di letteratura, la letteratura
i litterature » i litteraturen, i literature, _ litterature
agenda ii » agenda iii, agenda i, agenda iv

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: (( _ agenda ii iv letteratura e ) OR ( dei ((grani libro) OR (gran libro)) i litterature arte ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( _ agenda ii iv letteratura e ) or ( dei ((grani libro) OR (gran libro)) i litterature arte ))*".
