Spectroscopy in the Era of LSST
  This report summarizes the results of the 'Spectroscopy in the Era of LSST'
workshop held April 11-12, 2013 in Tucson, Arizona. At the workshop, there were
breakout sessions covering four broad science topics. These were: time domain
science, Galactic structure and stellar populations, galaxies and AGN, and dark
energy and cosmology. We present the science cases discussed in these breakout
sessions and provide a synthesis of highly desired capabilities that meet needs
across all four broad topics. We also present a table that will be useful to
characterize the needs of specific science cases in a format that provides a
general framework for discussion of future spectroscopic capabilities.
