The complexity of the high--temperature superconductors has required a remarkable refinement of experimental techniques in order to allow a reliable characterization of the samples, and is partly the reason why so many different microscopic models have so far been proposed.The book collects the lectures given at the CXXXVI Course of the ``Enrico Fermi International School on Superconductivity held in Varenna (Italy) on June 1997, which was aimed to give a pedagogical as well as an up-to date presentation of selected experimental and theoretical theories on the (so called) conventional superconductivity and on the high temperature superconductivity. For this reason we believe that it could be useful to young researchers who are entering this complex and rapidly evolving field as well as to more experienced scientists.The attention was focused on those reliable measurements which are expected to provide the theory with key constraints, viz: Raman and Infrared Spectroscopy, Nuclear Spin Resonance, Angular Resolved Photoemission Spectroscopy, transport measurements, Josephson effect.We believe that the lectures devoted to the overview of the BCS theory and to the discussion of minimal models and of the crossover from BCS to Bose-Einstein condensation may be particularly useful. The remaining part of the program is shared between phonon and non--phonon based mechanisms. On the one hand, special emphasis has been devoted to the breakdown of the Migdal theorem and to polaronic theories. On the other, the book contains an overview of stronglycorrelated electron theories, including magnetic interactions. A survey of the physics of vortices completes the theoretical part of the lectures.
