Some Developments in Light Quark Spectroscopy
  Among the many unresolved questions in light quark spectroscopy, the underlying structure of the scalar mesons and the identification of states with a gluonic content rank high. Recently, new information has come from $\phi$ radiative decays, $J/\psi$, $\tau$, $D$ and $D_s$ meson decays. Other papers in this conference review radiative transitions of $\phi$ and $J/\psi$. This paper discusses new information on the scalar sector primarily that from decays of $D$ and $D_s$ mesons.
