Abstract
We investigate the nonperturbative renormalization of composite operators i n lattice QCD restricting ourselves to operators that are bilinear in the q uark fields. These include operators which are relevant to the calculation of moments of hadronic structure functions. The computations are based on M onte Carlo simulations using quenched Wilson fermions.
