trf administration » csf administration, tariff administration, trade administration
2f administration » csf administration, self administration, delf administration
22great britain » great britain, xgreat britain, zgreat britain
et colonies » les colonies, ant colonies, its colonies
p colonies » les colonies, our colonies, ant colonies
_ 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: %22great britain %((((((p colonies) OR (her colonies))) OR (des colonies))) OR (((et colonies) OR (_ colonies)))) %((2f administration) OR (trf administration))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %((((((p colonies) OR (her colonies))) or (des colonies))) or (((et colonies) or (_ colonies)))) %((2f administration) or (trf administration))%22".
• Adding a wildcard symbol may retrieve word variants: %22great britain %((((((p colonies) OR (her colonies))) or (des colonies))) or (((et colonies) or (_ colonies)))) %((2f administration) or (trf administration))%22*.
