Perhaps you should try some spelling variations:
della letteratura » nella letteratura, e letteratura
letteratura arti » letteratura arte, letteratura sarda, letteratura di
y literatura » la literatura
graph libri » graph library, graph hybrid
libri della » libro della, libri dalla, libri nella
agenda ii » agenda iii, agenda i, agenda iv
ii graph » ii graphs, iii graph, i graph
ii y » ii _, ii a, ii 1

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 y literatura y ) OR ( ii graph libri della letteratura arti )).
• Adding a wildcard symbol may retrieve word variants: (( _ agenda ii y literatura y ) or ( ii graph libri della letteratura arti ))*.
