Perhaps you should try some spelling variations:
universitario del » universitarios del, universitario de, universitarios de
della biblioteca » la biblioteca
universitario en » universitaria en, universitaria y, universitaire en
una biblioteca » la biblioteca, _ biblioteca
del paso » el paso, del caso, del pasado
pluriverso » pluriverse, pluriversal

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: pluriverso – quadro ((della biblioteca) OR (una biblioteca)) del paso ((universitario del) OR (universitario en)) prato.
• The words AND, OR and NOT may confuse the search; try adding quotes: "pluriverso – quadro ((della biblioteca) or (una biblioteca)) del paso ((universitario del) OR (universitario en)) prato".
• Adding a wildcard symbol may retrieve word variants: pluriverso – quadro ((della biblioteca) or (una biblioteca)) del paso ((universitario del) OR (universitario en)) prato*.
