Perhaps you should try some spelling variations:
contribute della » contributo della, contributo delle, contribute all
contributi dalla » contributi alla, contributo della, contributo alla
historia antigua » historia antiqua, historia antiga
instituto de » institut der, institution der
istituto di » instituto ad
istituti di » instituti di, istituti pii, istituiti sic

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: %((contribute della) OR (contributi dalla))%((((istituto di) OR (instituto de))) OR (istituti di)) historia antigua%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((contribute della) OR (contributi dalla))%((((istituto di) or (instituto de))) or (istituti di)) historia antigua%22*".
