Perhaps you should try some spelling variations:
litterature arte » literature arts, literature art, letteratura arte
de litterature » la litterature, et litterature
e letteratura » y literatura, e literatur
gratia libro » statua libro, gran libro
agenda ii » agenda iii, agenda i, agenda _
agenda iv » agenda i, agenda iii, agenda _

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