Perhaps you should try some spelling variations:
specimina philologica » specimina philologiae, specimens philological
philosophiae slavicae » philologiae slavicae, philosophiae publice, philosophiae suae
philologica slavicae » philologica slavica, philologiae slavicae, 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 slavicae ) OR ( specimen philosophiae slavicae ))*.
