The records include annual reports, correspondence, memos, minutes, program files, news clippings, administrative records and photographs. They document the agency from its origins in a committee led by the Lenox Hill Neighborhood Association to its work during the 1990s providing social services to thousands of East Side residents. The founding and early history of the Stanley M. Isaacs Neighborhood Center are best documented by minutes in Series II, showing the collaboration between the New York City Housing Authority and the Lenox Hill Neighborhood Association to establish the agency. They also offer the most comprehensive view of administrative, fundraising and program decisions from the early years to the 1990s. This series is supplemented by architectural drawings and plans for the community center in Series VI. Program records in Series V focus on the period 1980-90, with a few items from the 1960s and '70s. The agency's fundraising efforts are documented in Series III, which includes correspondence with foundations and individuals, donor lists and committee files.
