The 1952 Year Book, like its predecessors, contains abstracts of what are considered by the editors to be the more important contributions in the various fields of internal medicine. The various sections, with the editors for each, are Infectious Diseases, Paul Beeson; The Chest, J. Burns Amberson; Blood and Blood-Forming Organs, William B. Castle; Heart and Blood Vessels and the Kidney, Tinsley Harrison; Digestive System, George Eusterman; Metabolism, Robert Williams. With such a distinguished group of editors it is not surprising that the selection of articles is excellent and the editorial comment regarding them interesting and helpful to the reader. For busy internists who find themselves unable to keep up with current developments in their field the Year Book is a perennial godsend. The present edition continues the fine tradition of this popular series.
