Perhaps you should try some spelling variations:
"specimens philological slavicae" » "specimina philologica slavicae", "specimen histological slavicae", "specimen pathological slavicae", "specimens philologica slavica", "specimens philologiae slavicae", "specimens philological polemical"
"specimen philologica slavicae" » "specimina philologica slavicae", "specimen histological slavicae", "specimen pathological slavicae", "specimen philologica slavica", "specimen philologiae slavicae", "specimen philologie slave"

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 (\"specimens philological slavicae\"))*".
• Removing quotes may allow a broader search: (( specimen philologica slavicae ) OR ( specimens philological slavicae ))*.
