We present spatially resolved GMOS spectroscopy for 13 of the closest E+A galaxies yet studied, at 0.005 < z < 0.04, representing a variety of morphological types. Caught in the brief E+A transition, these galaxies are evolving quickly from actively star-forming to passive early-type states, yet still allow us to separate the kinematics and distributions of their young and old stellar populations. In addition to global long-slit spectra for all the targets, we show 0.5 arcsecond resolution integral-field spectroscopy of the central kinematics and stellar populations of 5 objects. For the closest 3 targets, we present high-resolution optical/NIR imaging of the galaxies and their globular cluster systems. The proximity of our sample allows detailed comparison with numerical modelling of evolutionary processes. Together, these observations represent the most detailed study undertaken to date of a sample of E+A galaxies.
