Query: Basic considerations on broken-symmetry states of organic
  superconductors   In this brief account, we shall review the different mechanisms giving rise
to itinerant and localized antiferromagnetism in quasi-one-dimensional organic
conductors: the Bechgaard salts and their sulfur analogs. We will then focus on
the problem of spin correlations and their impact on the pairing mechanism for
organic superconductivity.
