This book is intended for postgraduate students, researchers and engineers engaged in research into oxide conductors. It presents an overview of electronic transport phenomena, including a discussion of high-Tc superconductivity and colossal magnetoresistance in two chapters, one of which reviews all the conducting oxides. In another nine chapters representative oxides are discussed in detail. Since electron-electron and electron-phonon interactions greatly influence conducting properties, two chapters are devoted to their explanation. More than 1200 references will serve as a useful guide to those entering into this vast field of research.
