Perhaps you should try some spelling variations:
letteratura storia » letterature storie, letteratura sarda, literatura historia
de letteratura » e letteratura, di letteratura, de litteratura
ii literatura » ii literature, iii literature, vii literature
ii literatur » vi literatur, viii literatur
grunde die » grunde der, grunde des, grundlage die

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 die de letteratura storia ) OR ( i grand livre ((ii literatura) OR (ii literatur)) de )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( i grunde die de letteratura storia ) or ( i grand livre ((ii literatura) OR (ii literatur)) de ))".
• Adding a wildcard symbol may retrieve word variants: (( i grunde die de letteratura storia ) or ( i grand livre ((ii literatura) OR (ii literatur)) de ))*.
