This book will become the standard work on the life and thought of emile Durkheim, one of the great founding fathers of sociology. Durkheim remains one of the most widely read thinkers in the social sciences and every student of sociology, anthropology and related subjects must study his now-classic books. He brought about a revolution in the social sciences: the defence of the autonomy of sociology as a science, the systematic elaboration of rules and methods for studying the social, the condemnation of racial theories, the critique of Eurocentrism and the rehabilitation of the humanity of 'the primitive'. He defended the dignity of the individual, the freedom of the press, democratic institutions and the essential liberal values of tolerance and pluralism. At the same time he was critical of laisser-faire economics and he defended the values of solidarity and community life. In many ways, Durkheim's rich intellectual heritage has become part of the self-understanding of our time.

Despite his enormous influence, the last major biography of Durkheim appeared more than 30 years ago. Since then, the opening up of archives and the discovery of manuscripts, correspondence with friends and close collaborators, administrative reports and notes taken by students have all provided a wealth of new material about his life and work. Meticulously documented, Marcel Fournier's new biography sheds fresh light on Durkheim's personality and character, his relationship with Judaism, his family life, his relations with friends and collaborators, his political and administrative responsibilities and his political views.

This book will be indispensable to students and scholars throughout the social sciences and will appeal to a wide readership interested in knowing more about the life and work of one of the most original and influential thinkers of the twentieth century.

Combined oxygen, in the form of water, metal oxides, silicates and other oxyions, accounts for about 50% by weight of the earth's crust. The chemistry of this most abundant element has two major aspects: that of water and aqueous solutions of electrolytes, and that of the solid state. The methodology and techniques appropriate for the study of these fields are sufficiently different that there have been very few points of contact between solution- and solid state chemists. One such contact, of great potential value, is provided by the extensive class of polyoxoanions formed by the transition metals of groups 5 and 6. As 'heteropoly and isopoly acids' these polyanions have been known and investigated for more than a century. The pre sent book is an attempt to survey the chemistry, structures, and applications of these species. Although the book forms part of a series in inorganic chemistry, the field of polyoxometalates deserves wider attention, for example, from organic chemists, especially those concerned with homogeneous and heterogeneous catalysis, and from biochemists, solid state- and materials scientists."
