self administration » welfare administration
2f administration » csf administration, trf administration, 8 administration
les colonies » des colonies, her colonies, _ colonies
2f colonies » _ colonies, p colonies, 4 colonies
et colonies » her colonies, des colonies, ant colonies

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: %great britain %((2f colonies) OR (((et colonies) OR (les colonies)))) %((2f administration) OR (self administration))%22.
• Adding a wildcard symbol may retrieve word variants: %great britain %((2f colonies) or (((et colonies) or (les colonies)))) %((2f administration) or (self administration))%22*.
