AMERICAN ASSOCIATION OF ADVERTISING AGENCIES, an organization comprised of approximately 140 of the leading advertising agencies in the United States and Can ada. For convenience the association is divided into five councils, one for each active business section of the country. The purposes of the association centre around the improvement of advertising and advertising procedure. It has promulgated a standard of ethics for the advertising business which is widely quoted and followed. Correction of such unethical practices as rebating, making false claims in advertising and unfair methods of soliciting business in its field has been one of the important activities of this association. The association maintains a research department which has made a survey of the national field in the study of duplication of periodical circulation. It maintains an export department which operates a rate and data file covering the entire world, primarily in the interests of the manufacturer or advertising agency which advertises in several countries. The association maintains a per sonnel bureau in which are registered a majority of those actively engaged in national advertising. This is probably the most exten sive bureau of its kind in existence. This association also acts as a clearing house for advertising information. While this service is maintained primarily in the interests of the members, it is prac tically free and open to all who have a legitimate use for the data it has on file. (H. E. A.)
