Perhaps you should try some spelling variations:
philosophiae slavicae » philosophiae publice, philosophiae suae, philosophie islamic
philologica slavicae » philologica slavica, philologie slave, philologica sive
philologiae slavicae » philologica slavica, 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 (philologiae slavicae)) ) OR ( specimen philosophiae slavicae ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( specimina ((philologica slavicae) OR (philologiae slavicae)) ) or ( specimen philosophiae slavicae ))*".
