Summary:

This volume contains the invited talks and contributed papers presented at the workshop on "Testing QCD Through Spin Observables in Nuclear Targets", held at the University of Virginia in April 2002.The workshop was proposed in the context of the large number of experiments that have used polarized deuterons or polarized 3 He to extract information about the spin parameters of the neutron. The motivation for this workshop was to study the effects of the nuclear medium on the spin properties of the bound nucleon and to explore issues in QCD that might be resolved through spin observables in nuc
