  Several speakers at IAU Symposium #187 (Cosmic Chemical Evolution) alluded to
the zeroth-order agreement between Type II supernovae (SNe) stellar yield
compilations, as predicted by the models of those most responsible for driving
progress in the field - i.e., Arnett (1991,1996); Maeder (1992); Woosley &
Weaver (1995); Langer & Henkel (1995); Thielemann et al. (1996). It is
important though for those entering (or indeed, already involved in!) the
chemical evolution field to be cognizant of the fact that there are important
first- and second-order differences between these compilations. In the next few
pages, I provide a qualitative comparison of the currently available Type II
SNe yield grids. The strengths and weaknesses of a given grid, demonstrated by
comparing against relevant observations, are noted. Some simple chemical
evolution models are shown which graphically demonstrate the effect of yield
grid selection.
