Harrison has provided a new text on the electronic structure and properties of solids. It is similar in spirit to his well-known 1980 text (Electronic Structure and the Properties of Solids) on the same subject but is otherwise entirely new. In covers covalent semiconductors, ionic insulators, simple metals, and transition-metal and f-shell-metal systems. It focuses on the most important aspects of each system, making what approximations are necessary in order to proceed analytically and obtain formulae for the properties. Such back-of-the-envelope formulae, which display the dependence of any property on the parameters of the system, are characteristic of Harrison's approach to electronic structure, as is his simple presentation and his providing all of the needed parameters. In spite of the diversity of systems and materials, the approach is systematic and coherent, combining the tight-binding (or atomic) picture with the pseudopotential (or free-electron) picture. This provides the parameters -- the empty-core radii as well as the covalent energies -- and conceptual bases for estimating the various properties of all of these systems. Extensive tables of the parameters and properties are included.
