This series primarily covers the years when William Ronan served Nelson Rockefeller as Secretary to the Governor, 1959 to 1966. From 1965 to 1966, Ronan also served as head of the Metropolitan Transit Authority. The bulk of this series is composed of reports prepared for Governor Rockefeller by various state departments and agencies. Some of these reports duplicate those found in Record Group 15, Series 28, Departmental Reports.

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.

This series contains a portion of Governor Nelson A. Rockefeller's political correspondence on state and national issues. The correspondence reflects his role as a national political figure and was filed separately from correspondence generated while serving as Governor of New York.

This series is made up of Nelson A. Rockefeller's personal copies of correspondence, reports, and other documents gathered during his service in the federal government in ten presidential appointments between 1940 and 1969. All manner of documents can be found in these files, from handwritten notes to printed reports. Marginal notes found in Rockefeller's handwriting are not uncommon. These records both duplicate and complement official government records held in the National Archives and in presidential libraries.
