Hardcover Abstract: In volume III/21 an attempt is made to compile the reported data on superconducting materi-als, from the discovery of this phenomenon to the present day. The data comprise various modifications of a material, e.g. bulk state, thin films,implanted films, filamentary wires and others. Where available,data obtained under high pressure or after high energy particle irradia-tion are also tabulated. The goal of this volume is to establish a complete and reliable compilation of critically reviewed experimental data, excluding pure theoretical work. A particular effort was made to present not only superconducting data for a given substance, but also the complete characterization of the analysed sample. The large number of publications, more than 40,000 since 1913, requires a subdivision of the data in seve
