Perhaps you should try some spelling variations:
specimina philologiae » specimina philologica, specimens philological, specimen philosophiae
philologiae slavicae » philologica slavica
philologica slavicae » philologica slavica
specimina philologie » specimina philologica, specimens philological
philologica sive » philologica de, theologica sive, philosophicae 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 slavicae) OR (philologica sive)) ) OR ( specimina philologie slave )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( specimina philologiae slavicae ) or ((( specimina ((philologica slavicae) OR (philologica sive)) ) or ( specimina philologie slave ))))".
• Adding a wildcard symbol may retrieve word variants: (( specimina philologiae slavicae ) or ((( specimina ((philologica slavicae) OR (philologica sive)) ) or ( specimina philologie slave ))))*.
