"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 philologica sive"
"specimen philologie slave" » "specimina philologiae slave", "specimen philosophiae slave", "specimina philologica 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: (((("specimen philologica slavicae") OR ("specimen philologie slave"))) OR ("specimens philological slavicae"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"specimen philologica slavicae\") OR (\"specimen philologie slave\"))) or (\"specimens philological slavicae\"))*".
• Removing quotes may allow a broader search: (((( specimen philologica slavicae ) OR ( specimen philologie slave ))) or ( specimens philological slavicae ))*.
