Perhaps you should try some spelling variations:
"acta slavica estonia" » "anna slavina estonia", "art slavic estonia", "et slavica estonia"
"et slovenia estonia" » "eu slovenia estonia", "art slovenia estonia", "ela slovenia estonia"
"acta latvia estonia" » "haiti latvia estonia"
"east slavic estonia" » "balto slavic estonia"

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: (((((("acta slavica estonia") OR ("et slovenia estonia"))) OR ("acta latvia estonia"))) OR ("east slavic estonia")).
• Removing quotes may allow a broader search: (((((( acta slavica estonia ) or ( et slovenia estonia ))) or ( acta latvia estonia ))) or ( east slavic estonia )).
• Adding a wildcard symbol may retrieve word variants: (((((("acta slavica estonia") or ("et slovenia estonia"))) or ("acta latvia estonia"))) or ("east slavic estonia"))*.
