Perhaps you should try some spelling variations:
"specimen philologica slavicae" » "specimens philological slavicae", "specimina philologica slavicae", "specimen histological slavicae", "specimen philologica slavica", "specimen philologiae slavicae", "specimen philologie slave"
"specimen philosophiae publice" » "specimen philosophy public"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"specimen philologica slavicae\") OR (\"specimen philosophiae publice\"))".
• Removing quotes may allow a broader search: (( specimen philologica slavicae ) OR ( specimen philosophiae publice )).
• Adding a wildcard symbol may retrieve word variants: (("specimen philologica slavicae") OR ("specimen philosophiae publice"))*.
