This series consists of a wide range of research files pertaining to mid-twentieth century issues of youth and race in New York City, predominantly in the neighborhood of Harlem. The files address subjects such as juvenile delinquency, school integration and decentralization, and institutional racism in foster care. The bulk of the files contain annotated photocopies of documents from relevant community organizations such as the Citizen's Committee for Children of New York City, Mobilization for Youth, Harlem Youth Opportunities Unlimited, and the Metropolitan Applied Research Center, as well as from notable individuals such as Dr. Kenneth B. Clark, Justice Justine Wise Polier, and Dr. Viola Bernard. These materials include reports, correspondence, and clippings. Also included is an extensive collection of documents from the Wilder v. Bernstein (i.e., Wilder v. Sugerman) court case, a class action lawsuit initiated by Judge Polier and filed on behalf of black, Protestant children in need of foster care in New York City.
