Health Advertisements Database from Ebling Sources (HADES)The Health Advertisements Database from Ebling Sources (HADES) consists of advertisements from health sciences journals covering the disciplines of medicine, nursing, pharmacy, hospital management, laboratory management, and the allied health sciences from 1923 to 2007. From small quarter page ads to full page drug ads, which often include the pharmaceutical indications, these advertisements offer a window into the clinical, social, economic, political, historical, legal, and cultural aspects of health care for several decades. Generally, from the United States, they also include British, French, German, and some non-European publishers.
