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

Try widening your search to All Fields.

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