This is an authoritative compendium of reviews of our present knowledge of personality structure and function. Each of the thirty-five chapters has been written by an expert in one or more of the biologic, experimental, psychologic, sociologic and psychiatric fields of personality study. The reviews are comprehensive, judicious and well documented, so that differences of interpretation and theory among the various contributors (as well as intriguing variations in point of view, vocabulary and literary style) can be fairly and profitably evaluated by the reader. The work has been expertly organized and edited, and the complete bibliographies and indexes make it an encyclopedic source of ready reference. These books deserve a place in the library of every psychiatrist, psychologist and sociologist; moreover, they will be welcomed by many a physician interested in modern scientific approaches to the normal or abnormal behavior of his friends and patients.
