  We present an extenstive literature compilation of age, metallicity, and
chemical abundance pattern information for the 41 Galactic globular clusters
(GGCs) studied by Schiavon et al. (2005). Our compilation constitutes a notable
improvement over previous similar work, particularly in terms of chemical
abundances. Its primary purpose is to enable detailed evaluations of and
refinements to stellar population synthesis models designed to recover the
above information for unresolved stellar systems based on their integrated
spectra. However, since the Schiavon sample spans a wide range of the known GGC
parameter space, our compilation may also benefit investigations related to a
variety of astrophysical endeavours, such as the early formation of the Milky
Way, the chemical evolution of GGCs, and stellar evolution and nucleosynthesis.
For instance, we confirm with our compiled data that the GGC system has a
bimodal metallicity distribution and is uniformly enhanced in the
alpha-elements. When paired with the ages of our clusters, we find evidence
that supports a scenario whereby the Milky Way obtained its globular clusters
through two channels, in situ formation and accretion of satellite galaxies.
The distributions of C, N, O, and Na abundances and the dispersions thereof per
cluster corroborate the known fact that all GGCs studied so far with respect to
multiple stellar populations have been found to harbour them. Finally, using
data on individual stars, we also confirm that the atmospheres of stars become
progressively polluted by CN(O)-processed material after they leave the main
sequence and uncover evidence which suggests the alpha-elements Mg and Ca may
originate from more than one nucleosynthetic production site. [abridged]
