Perhaps you should try some spelling variations:
philosophiae slavicae » philosophiae publice, philologica slavicae, philosophiae suae
philologiae slavicae » philologica slavicae, philologica slavica, philologie slave
specimen » specimens, species

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "specimen ((philosophiae slavicae) OR (philologiae slavicae))".
• Adding a wildcard symbol may retrieve word variants: specimen ((philosophiae slavicae) OR (philologiae slavicae))*.
