Perhaps you should try some spelling variations:
philosophiae slavicae » philologiae slavicae, philosophiae publice, philosophiae suae
speciess philosophiae » species philosophy, species philosophers, spencers philosophie
philologica slavicae » philologica slavica, philologiae slavicae, philologie slave
\"specimen » \"species
\"specimens » \"speciess, \"species

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: "((\"specimen philosophiae slavicae\") or ((((((\"specimens OR \"speciess) philosophiae slavicae\") OR (\"speciess philosophiae slavicae\"))) OR ((\"specimens OR \"speciess) philologica slavicae\"))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"specimen philosophiae slavicae\\") or ((((((\\"specimens OR \\"speciess) philosophiae slavicae\\") or (\\"speciess philosophiae slavicae\\"))) or ((\\"specimens OR \\"speciess) philologica slavicae\\"))))\"".
• Removing quotes may allow a broader search: (( specimen philosophiae slavicae ) or (((((( specimens OR speciess) philosophiae slavicae ) or ( speciess philosophiae slavicae ))) or (( specimens OR speciess) philologica slavicae )))).
