Perhaps you should try some spelling variations:
contributi dalla » contributi alla, contributo della, contributo alla
storia gotica » storia antica, storia politica, storia critica
instituto de » institut der, institution der
istituti pii » istituti di, istituiti sic, instituti di
istituto di » instituto ad

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: %contributi dalla%((((istituto di) OR (instituto de))) OR (istituti pii)) storia gotica%22.
• Adding a wildcard symbol may retrieve word variants: %contributi dalla%((((istituto di) or (instituto de))) or (istituti pii)) storia gotica%22*.
