Perhaps you should try some spelling variations:
di letteratura » e letteratura, de literatura, della letteratura
literatura de » literatura y, literatura en
y literatura » la literatura
i literatura » ii literatura, i literature, a literatura
grunde fir » grunde fur, grunde der, grunde die
livre i » livro i, livre 1, livre qui

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