Perhaps you should try some spelling variations:
"specimens philosophiae slavicae" » "species philosophy slavicae", "species philosophers slavicae", "specimens philological slavicae", "specimens philologiae slavicae", "specimens philologica slavicae", "specimens philosophiae suae"
"specimen philosophie islamic" » "medien philosophie islamic", "species philosophy islamic", "rechten philosophie islamic", "specimen philosophy islamic", "specimen philosophie bismarck"
"specimen philosophie analytic" » "medien philosophie analytic", "species philosophy analytic", "rechten philosophie analytic", "specimen philosophy analytic", "specimen philosophers analytic", "specimen philosophical analysis"
"specimen philosophiae publice" » "specimen philosophy public"
"specimina philologie slave" » "specimina philologiae slave", "specimina philologica slave", "specimens philological 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: (((((("specimen philosophie islamic") OR ("specimen philosophie analytic"))) OR ("specimen philosophiae publice"))) OR ((("specimens philosophiae slavicae") OR ("specimina philologie slave"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"specimen philosophie islamic\") OR (\"specimen philosophie analytic\"))) or (\"specimen philosophiae publice\"))) or (((\"specimens philosophiae slavicae\") or (\"specimina philologie slave\"))))*".
• Removing quotes may allow a broader search: (((((( specimen philosophie islamic ) OR ( specimen philosophie analytic ))) or ( specimen philosophiae publice ))) or ((( specimens philosophiae slavicae ) or ( specimina philologie slave ))))*.
