Extragalactic Globular Cluster Populations from High Resolution
  Integrated Light Spectra
  We present a comparison of high-resolution, integrated-light, detailed
chemical abundances for Galactic and extragalactic globular clusters in both
massive galaxies and dwarf galaxies. We include measurements of Fe, Ca, Si, Na,
and Al for globular cluster samples in the Milky Way, M31, Large Magellanic
Cloud, and NGC 5128. These and other recent results from our group on M31 and
NGC 5128 are the first chemical abundances derived from discrete absorption
features in old stars beyond the Milky Way and its nearest neighbors. These
abundances can provide both galaxy enrichment histories and constraints on
globular cluster formation and evolution.
