Spectroscopy -- An introduction and overview

The study of baryons can provide one with critical insights into the nature of QCD in the confinement domain. The key to progress in this field is the identification of its important degrees of freedom. The author explains why he believes that the adiabatic approximation is central to understanding the absence of gluonic excitations at low energies, and describe an extension of this approximation which can help one to understand the resiliency of the valence quark model to meson loop corrections. He closes with a survey of issues that he hopes to see resolved before Baryon 2001
