This volume consists of nine invited talks on the main subject of ceramic superconductors and other topics on organic superconductors and tunneling microscopy.
BiSrCaCuO high Tc superconductors, P. Monceau et al; metalorganic deposition of high Jc Ba2YCu3O7-x thin films on single crystal substrates, M.J. Cima et al; critical currents in proton irradiated YBa2Cu3O7-delta crystals, I. Civale et al; electron tunnelling in superconducting Ba-K-Bi-O - a review, R. Escudero; thermodynamic considerations in the Y-Ba-Cu-O system, H. Beyers and B.T. Ahn; review of organic conductors - a structural analysis, R.R. Schumaker; stepped copper surfaces observed by scanning tunneling microscopy, M.A. Huerta Garnica et al; experimental, predictions of the hole mechanism of superconductivity, F. Marsiglio; first principles cluster investigation of the electronic structures of copper oxide superconductors, M. Eto and H. Kamimura; oxygen ordering in YBa2Cu306+delta, J.L. Moran-Lopez and J.M. Sanchez; the importance of being n-type, P.M. Grant.
