Jeffrey A. Barrett, The Quantum Mechanics of Minds and Worlds. Oxford:

This book is a discussion of the Everett relative-state interpretation of quantum mechanics and related “no collapse ” interpretations. The book presumes that its readers will have some familiarity with quantum me-chanics and with the interpretational issues connected with it. It would be suitable for use in an introductory graduate course on the philosophy of quantum mechanics, although even experts are likely to enjoy its clear summaries of the material in its purview. The Dirac-von Neumann collapse postulate, which has it that a quan-tum system undergoes a state transition upon measurement that is radi-cally different from the continuous, linear, deterministic evolution it un-dergoes at all other times, has long been regarded as problematic. One of the problems to which it gives rise is the measurement problem, the problem of explaining what it is that distinguishes measurements from other physi-cal interactions. If the collapse postulate is rejected, however, we are faced with the problem of accounting for determinate outcomes of experiments
