Abstract: Records of the Infant Formula Action Coalition (INFACT), a citizen action group formed in the United States in 1976, documenting the organization's activities related to addressing social problems by altering the behavior of corporations. Their first campaign (1977-1984) was aimed at changing the corporate marketing practices of infant formula in the United States and in Third World countries which led to the boycott of the Swiss-giant Nestlé Corporation. The second major campaign (1984-1993) was aimed at exposing corporate connections to nuclear weapons build-up which led to a boycott against the General Electric Company (GE). Also documented are the activities of other support organizations and the grassroots efforts of regional INFACT campaign centers; infant formula marketing, infant nutrition, and breastfeeding in various developing countries; the lawsuit filed by the Sisters of the Precious Blood against Bristol-Myers; nuclear weaponry; and environmental health issues.
