trf administration » tariff administration, trade administration, self administration
csf administration » self administration, unis administration, union administration
zgreat britain » great britain, xgreat britain, great brittain
2f colonies » p colonies, de colonies, 14 colonies
et colonies » her colonies, des colonies, les colonies
4 colonies » p colonies, de colonies, 4 colonial
_ colonies » _ colonial

Try widening your search to All Fields.

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: %zgreat britain %((((2f colonies) OR (4 colonies))) OR (((et colonies) OR (_ colonies)))) %((csf administration) OR (trf administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%zgreat britain %((((2f colonies) OR (4 colonies))) or (((et colonies) or (_ colonies)))) %((csf administration) or (trf administration))%22".
• Adding a wildcard symbol may retrieve word variants: %zgreat britain %((((2f colonies) OR (4 colonies))) or (((et colonies) or (_ colonies)))) %((csf administration) or (trf administration))%22*.
