universitario de » universitario del, universitaria de, universitarios del
biblioteca del » biblioteca della

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: pluriversal – quaderni _ ((biblioteca del) OR (biblioteca di)) governo ((universitario de) OR (universitarios de)) prima.
• The words AND, OR and NOT may confuse the search; try adding quotes: "pluriversal – quaderni _ ((biblioteca del) OR (biblioteca di)) governo ((universitario de) or (universitarios de)) prima".
• Adding a wildcard symbol may retrieve word variants: pluriversal – quaderni _ ((biblioteca del) OR (biblioteca di)) governo ((universitario de) or (universitarios de)) prima*.
