This Workshop took place after the International Conference on Materials and Mechanisms of Superconductivity - High Temperature Superconductors III (Kanazawa, 22-27 July 1991) and attracted some of the most distingusihed participants from that major event. From the conference some key areas were selected and discussed at the workshop in great detail. These include cuprate superconductors and a new class of high-T c M x C 60 . The investigation of the similarity and dissimilarity between the properties of both superconductors may lead to an understanding of the mechanism of high-T c superconductivity. Papers on the superconducting properties of the cuprate oxides related to the flux-lines and their dynamics are also included. This carefully edited volume is therefore a very readable account of some of the most important aspects of high-T c superconductivity as seen by the leading authorities in 1991. It can be highly recommended for its originality as well as its archival value.
