Perhaps you should try some spelling variations:
specimina philologica » specimina philologiae, specimens philological
specimina philologie » specimina philologiae, specimens philological
philologica slave » philologica sive, philologica slavicae, filologia slava
slavica » slavicae, slavic

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 philologie slave ) OR ((( specimina philologica slave ) OR ( specimina philologica slavica ))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( specimina philologie slave ) or ((( specimina philologica slave ) OR ( specimina philologica slavica ))))*".
