The authors discuss some of the current issues on the copper-free layered perovskite superconductor Sr{sub 2}RuO{sub 4}, for which a sharp transition at T{sub c} = 1.2 K has been reproducibly obtained. The normal state is characterized as an essentially two-dimensional Fermi liquid, and the coherent interlayer transport is established only at low temperatures. The cylindrical Fermi surface observed by de Haas-van Alphen experiments is consistent with other thermodynamic and transport properties. Although the specific heat jump across T{sub c} confirms the bulk superconductivity, the large residual T-linear term which correlates with the variation in T{sub c} is unusual and suggestive of unconventional pairing.
