The old dream of organic superconductivity was finally realized in 1980, but hopes for high transition temperatures have not been fulfilled as yet. We review the phenomenon of superconductivity and the present understanding of the microscopic theory with emphasis on molecular conductors. The historical development is briefly described. We discuss how the common approach to making molecular conductors almost invariably leads to materials that are highly anisotropic, in some cases even quasi-one-dimensional. Quasi-one-dimensional conductors are susceptible to various instabilities and up till now superconductivity has only been found in two groups of related materials with a maximum superconducting temperature around 12 K. The structure and the physical properties of the materials are presented in relation to the occurrence of superconductivity.
