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

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 philologica sive") OR ("specimina philologica slavica"))) OR ("specimens philologiae slavicae"))*.
• Removing quotes may allow a broader search: (((( specimina philologica sive ) or ( specimina philologica slavica ))) or ( specimens philologiae slavicae ))*.
