The Activities Series provides a partial view of Nelson A. Rockefeller's business, civic, governmental, philanthropic, cultural, and social activities from 1930 to 1979. The records in this series were assembled by the Rockefeller family archivist during the early 1970s following the 1971 transfer of Nelson A. Rockefeller's files to the Rockefeller family archive. The bulk of material dates from between 1946 and 1971, a period when Rockefeller maintained his files separately from the General Files of the Office of the Messrs. Rockefeller, which contained the files of his father and brothers. Records predating 1946 were removed from the General Files in that year to form the core of Nelson A. Rockefeller's files. Most of Nelson A. Rockefeller's personal files created after 1971 are in Record Group 3 and 33 of the Rockefeller family archives,which remain closed to research. However, for reasons which are not now known, some records created after 1971 were filed at the end of this series. They are designated "Post-1971 Material." The title of the series reflects the broad scope of the documentation.
