Abstract
In this talk I will discuss a number of approaches designed to deal with the
problem of setting up a fully non-perturbative renormalization procedure in
lattice QCD. Methods based on Ward-Takahashi identities on hadronic states, on
imposing chiral selection rules on amplitudes with external quark/gluon legs,
on the use of the Schrödinger functional and on ``heating and cooling''
Monte Carlo steps are reviewed. I conclude with some remarks on the possibility
of defining next order terms (higher twists, ``condensates", ...) in short
distance expansions.
