Abstract

We review the properties of quasi-one-dimensional organic superconductors: the Bechgaard salts and their sulfur analogs in their normal phase precursor tolong-range order. We go through the main observations made in the normal state of these systems at low magnetic field and tackle the issue of their description under the angles of the Fermi and Luttinger liquid pictures.
