Perhaps you should try some spelling variations:
"bibliothecae mediceae" » "biblioteca medicea", "bibliothecae regiae", "bibliotheca indica"
"bibliothecae selectae" » "bibliothecae regiae", "bibliothecae publicae"
"bibliotheca selecta" » "bibliotheca selectissima", "bibliotheca sacra", "bibliotheca asservata"

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 ("bibliotheca selecta")))).
• Removing quotes may allow a broader search: (( bibliothecae mediceae ) or ((( bibliothecae selectae ) or ( bibliotheca selecta )))).
• Adding a wildcard symbol may retrieve word variants: (("bibliothecae mediceae") or ((("bibliothecae selectae") or ("bibliotheca selecta"))))*.
