This book is based on the Proceedings of the 9th European Workshop on White Dwarfs, the most recent in a series of meetings which have become the most important events in this field. Many of the contributions, however, have been expanded considerably by the authors to include introductory material. This makes this volume a useful, up-to-date introduction into the present status of observations and theory of white dwarf stars.
