very useful, comprehensive, spanning a spectrum that includes phenomenology and history, microscopic theory, high-temperature superconductivity, and applications sections on the macroscopic wave function, describing the superfluid behavior of the electrons, the Ginzburg-Landau model, and the Josephson effects contain unique physical insights. Especially noteworthy are the treatments of electron-phonon coupling, the relationship of the order parameter to the microscopic theory, and the nonlocal form of the BCS theory. a heroic effort to cover the current understanding and present in a fair manner the various positions on many questions. Particularly strong are the considerations of electronic structure issues, properties of the normal state, and issues such as the spin gap and the pseudogap. essential physical ideas are outlined, and the references provide a clear path into the various subfields for the interested reader. The comparison of the properties of the cuprates with BCS theory is an excellent summary of a large number of experimental studies a fine job in reviewing the experimental facts contains many profound physical insights and a comprehensive introduction to a wide variety of topics certainly should be read by serious students of the subject.
It is true that much of the intrinsic beauty of superconductivity is that it is basically a quantum mechanical phenomenon and any thorough treatment has to tackle this head on. John Waldram has met this challenge admirably an impressive contribution and worthy of its subject. I can not recommend it too highly.
