Query: Comment on: 'Depolarization corrections to the coercive field in
  thin-film ferroelectrics'   The Letter by Dawber et al. [J. Phys.: Condens. Matter 15 L393 (2003)] notes
that incomplete screening in the electrodes of a ferroelectric capacitor can
result in an underestimate for the true coercive field in films of nanometer
thickness. We show that their estimate of the magnitude of this correction it
too large in the case of ferroelectric copolymer Langmuir-Blodgett films and,
as a result, invalidates the claim that finite-size scaling of the
ferroelectric coercive field is evident in films thinner than 15 nm.
