Hardcover Abstract: Photoelectron spectroscopy has matured considerably during the last decade. The experimental techniques were improved markedly. Photon line sources and,in particular, synchrotron radiation sources are now routinely available in many places. The volume summarizes data on the bulk electronic structure of solids. Besides the photoelectron results, a limited set of other data (such as lattice constants and work functions) useful in the context of band structure information is presented.
