Part 3 of the Harsch Papers has been arranged in two sections: Correspondence and Personal Papers, and Broadcast Scripts and Article Drafts.

Harsch's CORRESPONDENCE AND PERSONAL PAPERS include several folders of general correspondence from friends and business associates, mainly pertaining to his reporting, broadcasting, writing, and related travel arrangements; letters sent to the Christian Science Monitor in response to Harsch's columns, and drafts of Harsch's replies to the latter. There are also individual folders of correspondence with major radio and television networks concerning Harsch's broadcasting commitments and with the Christian Science Monitor, other journals, and Harsch's publishers. Many of the folders include small quantities of news clippings about Harsch, contracts, royalties statements, and drafts of articles. There are similar materials documenting Harsch's European trips in 1953, 1955, 1956, and 1957, including his first trip to the Soviet Union in 1955.

Harsch's other personal papers include congratulatory letters, news clippings, and other papers about the DuPont Award, which Harsch won in 1952; personal income and expenses reports; and income tax returns and papers. For many years, Harsch maintained a busy schedule of personal lectures in addition to his broadcasting and writing commitments, generally speaking on foreign affairs topics. Included in the collection are correspondence regarding invitations to speak, arrangements, and fees, both with individual groups and with Harsch's agent, together with contracts, notes, outlines, and speeches.

BROADCAST SCRIPTS AND ARTICLE DRAFTS comprise the second series in the 1987 additions. Scripts and drafts are filed in reverse chronological order, and arranged by network, journal, or topic. Most of the drafts are typewritten carbons and have been annotated by Harsch. Included are scripts for ABC Reports, 1967-1970; scripts from a few broadcasts for the British Broadcasting Corporation and the Canadian Broadcasting Corporation; many drafts of Harsch's Christian Science Monitor column, 1967-1979; a few drafts of articles about John Foster Dulles and Harsch's series on the Pacific, reporting about World War II; drafts of articles written during and describing his 1955 European trip; NBC broadcast scripts, 1956-1957; and scripts for Reports From America, prepared for the United States Information Agency for broadcast in Europe.
