"bibliothecae mediceae" » "biblioteca medicea", "bibliothecae regiae", "bibliotheca indica"
"bibliothecae selectae" » "bibliotheca selecta", "bibliothecae regiae"
"bibliothecae publicae" » "bibliotheca publica", "bibliotheque publique", "bibliotheca anglica"

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: (("bibliothecae mediceae") OR ((("bibliothecae selectae") OR ("bibliothecae publicae")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"bibliothecae mediceae\") or (((\"bibliothecae selectae\") OR (\"bibliothecae publicae\"))))".
• Removing quotes may allow a broader search: (( bibliothecae mediceae ) or ((( bibliothecae selectae ) OR ( bibliothecae publicae )))).
• Adding a wildcard symbol may retrieve word variants: (("bibliothecae mediceae") or ((("bibliothecae selectae") OR ("bibliothecae publicae"))))*.
