The Microfilm Subseries contains correspondence, documents, newspapers, and writings of Wilson and others which had been microfilmed by various repositories and purchased by the editorial staff for reference and inclusion in the Papers of Woodrow Wilson Project. Repositories from which significant amounts of reels were purchased include the Library of Congress, the National Archives, the London Public Records Office, Princeton University, and Yale University. This subseries is closely related to Subseries 1C: Miscellaneous Photocopies, in that similar types of materials are included in both subseries, although there is little or no overlapping content.

The Administrative Files subseries documents D's management of the development projects in Iran. The majority of the files are composed of correspondence, and also include financial and personnel records, reference materials on Iran, and records pertaining to D's interaction with the International Bank for Reconstruction and Development (IBRD) and with the Khuzestan Water and Power Authority (KWPA). The subseries also includes the previous finding aid for the Khuzestan Development Program records, written by Thomas Mead of D, which contains descriptions of the content of most folders and information about D's history in Iran. Please note, however, that the records have been re-organized since this finding aid was written.
