This book presents contributions from the Workshop on Rare Isotopes and Fundamental Symmetries, which was held on September 19-22, 2007, at the Institute for Nuclear Theory at the University of Washington. The book is the fourth in a series dedicated to exploring the science important to the proposed Facility for Rare Isotope Beams (FRIB). The topics covered by the contributions include Fermi beta decay, electron-neutrino correlations in nuclear beta decay: precision mass measurements, atomic parity violation, electric dipole moments, and hadronic parity violation and anapole moments.These topics highlight the recent work on the use of nuclei to understand the fundamental symmetries of nature. It presents current results as well as proposals for future experiments.
