Perhaps you should try some spelling variations:
specimina philologica » specimina philologiae, specimens philological
"Specimina philologica slavica" » "Specimina philologica slavicaea", "Specimina philologiae slavicaea", "Specimina philologie slavea"
"Specimina philologica slavic" » "Specimina philologica slavicae", "Specimina philologiae slavicae", "Specimina 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: "((\"Specimina philologica slavica\") OR (\"Specimina philologica slavic\"))*".
• Removing quotes may allow a broader search: (( Specimina philologica slavica ) OR ( Specimina philologica slavic ))*.
