Perhaps you should try some spelling variations:
de letteratura » e letteratura, de litteratura, de litterature
di letteratura » e letteratura, de literatura, della letteratura
ii literatura » ii literatur, ii literature, iii literature
livre ii » livres ii, livre iii, livre i

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 grunde fur ((de letteratura) OR (di letteratura)) sarda ) OR ( i grand livre ii literatura y )).
• Adding a wildcard symbol may retrieve word variants: (( i grunde fur ((de letteratura) or (di letteratura)) sarda ) or ( i grand livre ii literatura y ))*.
