Perhaps you should try some spelling variations:
contributor della » contributo della, contributor delete, contributo alla
contributo delle » contributo della, contributor table
istituiti sic » istituti di, istituti pii
storia antica » storia gotica, storia romantica, historia antiga
istituto di » instituto de, instituto ad

Try widening your search to All Fields.

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: %((contributor della) OR (contributo delle))%((istituto di) OR (istituiti sic)) ((storia antica) OR (storia romanza))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((contributor della) OR (contributo delle))%((istituto di) or (istituiti sic)) ((storia antica) or (storia romanza))%22".
• Adding a wildcard symbol may retrieve word variants: %((contributor della) OR (contributo delle))%((istituto di) or (istituiti sic)) ((storia antica) or (storia romanza))%22*.
