Study of Z' Couplings to Leptons and Quarks at NLC
  The discovery of a Z' and the measurement of Z' couplings to fermions are main tasks of future colliders. Here, the possibilities to measure Z' f \bar f couplings at an NLC operating below a Z' resonance are studied. In dependence on the mass of the Z' and the collider parameters one will be able to discriminate between Z' models.
