  His book The Quantum Mechanics of Minds and Worlds (Oxford University Press, 2000) concerns this problem and its solutions, and his book with Peter Byrne, The Everett Interpretation of Quantum Mechanics: Collected Works 1955-1980 with Commentary (Princeton University Press, 2012) collects the works of Everett himself on this problem.
