  This lecture describes the treatment of heavy quarks in lattice QCD by
implementing the Isgur-Wise limit. The method is briefly discussed, and some of
the special features of the resulting theory are highlighted. We emphasize
issues of the renormalization of the effective theory. The formulation permits
a calculation of heavy quark processes even when the momentum transfers are
much larger than the inverse lattice spacing. Applications include
semi-leptonic heavy quark decay and scattering processes, including the
computation of the nonperturbative part of the Isgur-Wise universal function.
