Photoelectron spectroscopy has matured considerably during the last decade. The experimental techniques were improved impressively and a deeper theoretical insight into the underlying mechanisms of photoemission could be achieved. The present volume III/23C2 is a critically and as comprehensive as possible tabulation of data on the bulk electronic structure of magnetic transition metals, obtained by electron and photon spectroscopies. This volume presents, besides the photoelectron results, and calculated dispersion curves, also a limited set of other data like lattice constants and work functions useful in the context of band structure information. Tables of frequently used symbols and of abbreviations are given in a general introduction where also definitions of the quantities and some historical remarks are included.
