Perhaps you should try some spelling variations:
instituto lombardo » istituto lombardo, instituto oswaldo
accademia di » academia _
di letters » di lettere, i letters, xi letters
ii letters » 2 letters
scienza di » scienza dei, scienze di, scienza del

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: "((\"instituto lombardo accademia di scienze ((di letters) OR (ii letters))\") or (\"instituto lombardo accademia di ((scienza di) OR (scienza e)) letters\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"instituto lombardo accademia di scienze ((di letters) OR (ii letters))\\") or (\\"instituto lombardo accademia di ((scienza di) or (scienza e)) letters\\"))\"".
• Removing quotes may allow a broader search: (( instituto lombardo accademia di scienze ((di letters) OR (ii letters)) ) or ( instituto lombardo accademia di ((scienza di) or (scienza e)) letters )).
