This is a valuable reference book of information regarding hospitals and related institutions of the United States, its possessions, and the Dominion of Canada. The main section is a list of the hospitals that are recognized in the American Medical Association's Register of Hospitals. It gives information regarding each of these institutions that has not been compiled elsewhere, especially history, organization and special services provided. The orderly arrangement facilitates finding the desired data. Other sections are equally informative. These include (1) a description of each of the fifty-six medical and hospital organizations that are active in the hospital field, (2) state, regional and local hospital associations and councils and associations of superintendents, and (3) standards for hospitals, including those of the American College of Surgeons, the American Medical Association and other standardizing agencies.
