  The application of quark models to the spectra and strong and electromagnetic
couplings of baryons is reviewed. This review focuses on calculations which
attempt a global description of the masses and decay properties of baryons,
although recent developments in applying large N_c QCD and lattice QCD to the
baryon spectrum are described. After outlining the conventional
one-gluon-exchange picture, models which consider extensions to this approach
are contrasted with dynamical quark models based on Goldstone-boson exchange
and an algebraic collective-excitation approach. The spectra and
electromagnetic and strong couplings that result from these models are compared
with the quantities extracted from the data and each other, and the impact of
various model assumptions on these properties is emphasized. Prospects for the
resolution of the important issues raised by these comparisons are discussed.
