Records of one of the oldest schools of social work in the United States, founded in 1898 as the New York School of Philanthropy and affiliated with the Charity Organization Society of New York City. The school merged with Columbia University in 1959, becoming the Columbia University School of Social Work. This collection includes the records of the office of the Dean, Development and Alumni Relations, and the Social Work Library, the bulk of which date from the 1930s through the 1980s.
