Series II: Administrative Records, 1921-2010 contains memos, reports, and other records relating to the management of the NYBC. Much material is available on the Board of Directors and the Council of Presidents. The many different committees of the NYBC are documented here, especially the Building Industry Practices Committee, the Executive Committee and the Membership Committee. Committee files include agendas, correspondence, and meeting packets. Although none of the records are without gaps, the best coverage is of the 1950s-1990s. President Richard T. Anderson's chronological file consists mostly of his correspondence, but also includes memos, reports, and other documents.
