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

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