Perhaps you should try some spelling variations:
"specimina philologica slavic" » "specimina philologiae slavic", "specimens philological slavic", "specimina philologica slavica", "specimina philologiae slavicae", "specimina philologie slave"
"specimina philologica slavicae" » "specimina philologiae slavicae", "specimens philological slavicae", "specimina philologica slavica", "specimina philologie slave", "specimina philologica slavicaae", "specimina philologiae slavicaeae", "specimina philologie slaveae"

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: "((\"specimina philologica slavic\") OR (\"specimina philologica slavicae\"))*".
• Removing quotes may allow a broader search: (( specimina philologica slavic ) OR ( specimina philologica slavicae ))*.
