In the mid-1970s, aging became a popular, even a fashionable topic. Professors made efforts to add gerontology to their teaching competence. And many colleges introduced courses in gerontology, or courses on aging-related aspects within the fields of psychology, sociology, psychiatry, public health, and nursing. Jack Bot-winick published in 1973 his textbook Aging and Behavior, with a new edition in 1978 and a third one in 1984. For the planning of future volumes the board had regular meetings held at the annual conventions of the Gerontological Society of America (G.S.A.), usually one of the mornings. This project lived and continues through 28 years and brought much prestige, good new authors, and some money to Springer. The large field was subdivided into its disciplines: psychology, psychiatry, medicine, nursing, public health, social work; and the expert board members were asked to assemble lists of terms that should form the body of the encyclopedia.
