Perhaps you should try some spelling variations:
historia antigua » historia antiqua
contributi dalla » contributi alla, contributo della, contributo alla
historia antiga » historia antiqua, historia argentina
istituto di » instituto de, 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: %contributi dalla%((istituto di) OR (istituti di)) ((historia antiga) OR (historia antigua))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%contributi dalla%((istituto di) or (istituti di)) ((historia antiga) OR (historia antigua))%22".
• Adding a wildcard symbol may retrieve word variants: %contributi dalla%((istituto di) or (istituti di)) ((historia antiga) OR (historia antigua))%22*.
