Perhaps you should try some spelling variations:
"specimens philological slave" » "specimina philologica slave", "specimen histological slave", "specimen pathological slave", "specimens philologica sive", "specimens philologica slavicae", "specimens philological essays"
"specimina philologie slave" » "specimina philologiae slave", "specimina philologica slave"

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: "((\"specimina philologie slave\") OR (\"specimens philological slave\"))*".
• Removing quotes may allow a broader search: (( specimina philologie slave ) OR ( specimens philological slave ))*.
