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

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: (((("specimina philologiae slavicae") OR ("specimina philologica slavica"))) OR ("specimina philologica slavicae"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specimina philologiae slavicae\") OR (\"specimina philologica slavica\"))) or (\"specimina philologica slavicae\"))*".
• Removing quotes may allow a broader search: (((( specimina philologiae slavicae ) OR ( specimina philologica slavica ))) or ( specimina philologica slavicae ))*.
