Abstract
We use two-dimensional QCD as a toy laboratory to study off-forward parton distributions (OFPDs) in a covariant field theory. Exact expressions (to le ading order in 1/N-C) are presented for OFPDs in this model and are evaluat ed for some specific numerical examples. Special emphasis is placed on comp aring the x>zeta and x<<zeta> regimes as well as on analyzing the implicati ons for the light-cone description of form factors.
