The combination of lowered dimensionality and electron-electron correlations are responsible for the unusual temperature and frequency dependence of the electrical conductivity of the new superconductors. The authors first review the electrodynamics of two systems, U{sub 2}Ru{sub 2}Si{sub 2} and Sr{sub 2}RuO{sub 4} where conventional Fermi liquid ideas seem to work. Here transport is by free carriers with strongly renormalized masses. On the other hand the electrodynamics of the high {Tc} cuprates and the organic charge transfer salts is unconventional. The high {Tc}`s show a Drude peak with an anomalous temperature and frequency dependent scattering rate for the in-plane conductivity, while normal to the planes they are almost insulating. In the organics, the transport currents are carried by a narrow collective mode coupled to phonons. 44 refs., 7 figs.
