I first learned of the existence of this book on high-temperature superconduc- tivity when I received a copy in the office of one of the co-editors, Prof. V. L. Ginzburg, shortly after publication. I had known of the work on problems and prospects of achieving high-temperature superconductors by the members of the I. E. Tamm Department of Theoretical Physics of the P. N. Lebedev Physical Institute. I was naturally anxious to read and study this volume, which inte- grates the work of more than a decade. Lest one think that the contributions contained here are of the nature of a reflective...
