A Classified Bibliography of Gerontology and Geriatics

541 regard to the anoxic, toxemic, and neurogenic factors involved in shock, without arbitrarily resolving justifiable differences of opinion about these factors as they are conceived by the investigators whose works he cites. Somewhat neglected by understatement, however, are the evidences of Eversole, Swingle, Wang, and others on the role of the nervous system in the dynamic evolution of shock. Professor Wiggers' superb analysis of the hemodynamic factors, and his very able judgment in interpreting the multiple factors involved in shock, combine to make this a very valuable monograph. He does not hesitate to prescribe suspended judgment on controversial points, and he concludes the monograph with an outline of important channels of research which in his opinion will need to be developed in order to bring an understanding of the physiology of shock to a reasonably complete solution. He makes the important point that clinical practices in reference to the treatment of shock should not be predicated on the idea that a single type of treatment is indicated during all stages of shock. Because this book comes at a time when battle casualties are dying of shock and when the inhabitants of the major cities of the world face the threat of assault by mass destruction weapons, this very provocative volume constitutes a worthy and timely contribution. The introduction very appropriately begins: "The rising interest in gerontology has focused attention on the scarcity of bibliographic and summary material in the field. Since the problems of gerontology extend from the question of changes in enzyme systems within individual cells to important social and economic problems of methods and techniques for the utilization of the capacities of elderly people, practically every scientific and clinical discipline may offer facts and observations of importance. Although some aspects of the field have been summarized and a few special bibliographies have appeared, there is a conspicuous lack of recent comprehensive bibliographic material on the subject of gerontology." This is a carefully prepared and much needed reference book on the bibliography of gerontology and geriatrics and will be a valuable addition for medical libraries and research workers. There are six main headings: in turn are subdivided into two and sometimes three smaller divisions. The main text is followed by a key to Abbreviations of Journals Cited of more than 2,300 journals and by indices to authors and subjects. An excellent feature of this fine bibliography is that …
