Perhaps you should try some spelling variations:
"specimens philosophiae slavicae" » "species philosophy slavicae", "species philosophers slavicae", "specimens philological slavicae", "specimens philologiae slavicae", "specimens philologica slavicae", "specimens philosophiae suae"
"specimen philosophiae slavicae" » "specimen philologiae slavicae", "specimen philologica slavicae", "specimen philosophiae suae"
"specimen philosophiae publice" » "specimen philosophy public"

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: (((("specimen philosophiae slavicae") OR ("specimen philosophiae publice"))) OR ("specimens philosophiae slavicae"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specimen philosophiae slavicae\") OR (\"specimen philosophiae publice\"))) or (\"specimens philosophiae slavicae\"))*".
• Removing quotes may allow a broader search: (((( specimen philosophiae slavicae ) OR ( specimen philosophiae publice ))) or ( specimens philosophiae slavicae ))*.
