"specimens philological slave" » "specimina philologica slave", "specimen pathological slave", "specimina philologiae slave", "specimens philologica sive", "specimens philologica slavicae", "specimens philological essays"
"specimen histological slavicae" » "specimen pathological slavicae", "special histologic slavicae", "aspects histological slavicae", "specimen histological slices", "specimen philologica slavicae", "specimen histological staging"
"specimina philologie slave" » "specimina philologiae slave", "specimina philologica 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 histological slavicae") OR ((("specimina philologie slave") OR ("specimens philological slave")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"specimen histological slavicae\") or (((\"specimina philologie slave\") OR (\"specimens philological slave\"))))".
• Removing quotes may allow a broader search: (( specimen histological slavicae ) or ((( specimina philologie slave ) OR ( specimens philological slave )))).
• Adding a wildcard symbol may retrieve word variants: (("specimen histological slavicae") or ((("specimina philologie slave") OR ("specimens philological slave"))))*.
