The Princeton Years series documents Crespi's career prior to joining the USIA . It includes correspondence, research notes, clippings, reports, and published articles relating to Crespi's graduate research at Princeton on gambling addiction, his research on German public opinion of the United States, and other research projects on topics such as such tipping in America and the Kinsey Reports. Also included is correspondence relating to his professorship at Princeton in the psychology department, and his time at UCLA as an undergraduate.

This series documents Crespi's career after joining the USIA in 1954. This series includes USIA reports and related correspondence, notes, and clippings on surveys of foreign and domestic public opinion on a wide range of subjects, including the U.S. economy, trends in political thought, the future of American foreign policy, NATO, U.S. exhibitions on other countries, moral equivalence, phased retirement, and the effectiveness of USIA's own programs and surveys. Surveyed regions include Western and Eastern Europe, the Mideast, Asia, Latin America, and North America. Also included are departmental files of the USIA Office of Research (including service awards and performance evaluations of Crespi), WAPOR newsletters and correspondence, personal correspondence, photographs, biographical sketches of Crespi, drafts of published articles, and notes and related correspondence for various presentations and lectures he conducted over the course of his career. Material in this series that pre-dates 1954 primarily consists of USIA material that Crespi utilized in his research, as well as one report co-authored by Crespi for the office of the U.S. High Commissioner for Germany.

The Biographical series primarily comprises drafts of Coale's autobiography, published in 1995. Other items include press clippings related to Coale and his family, Coale's Curriculum Vitae, the text of an interview of Coale, records of his extensive travels around the world for demographic studies, and personal correspondence. See also Series 7: Media.

The Project Data series mostly contains handwritten notes. Little information is available about the creation or use of the documents.

The Biographical and Personal series consists of approximately 0.5 linear feet of material and includes biographical information, as well as material related to Kirkpatrick's time at Princeton University and other non-professional activities. Of special note is a 185-page biography compiled by Kirkpatrick's wife Rita, which makes use of documents found elsewhere in the collection. The majority of correspondence found in the series is a group of photocopies of letters compiled by Kirkpatrick's wife Rita into a "significant signatures file." The file includes correspondence from U.S. presidents and vice presidents, senators and representatives, and military officers including Omar Bradley. The vast majority of the correspondence in the Significant Signatures File is brief and insubstantial; many of the letters are holiday greetings, invitations, or congratulations on Kirkpatrick's retirement from the CIA or Brown University. There is some correspondence related to Kirkpatrick's intelligence career, including a brief letter in which newly appointed Director of Central Intelligence George H.W. Bush comments on the struggles ahead of him. The series also includes a small folder of photographs, primarily of Kirkpatrick during his military service and years with the CIA.

The World War II series documents Kirkpatrick's service in the Office of Strategic Services and U.S. Army during World War II. Approximately half of the series consists of reports and studies on the activities of the German army and General Omar Bradley's 12th Army Group. Kirkpatrick wrote at least one of the studies ("Destruction of the German Armies in Western Europe, June 6, 1944 - May 9, 1945"). Other highlights in the series include a group of progress reports and daily summaries which appear to have been written by Kirkpatrick during his time in the OSS, the text of a Kirkpatrick speech which appears to have been broadcast to the United States on V-E Day, and photocopies of Kirkpatrick's personnel records.

The Writings series consists of correspondence, notes, and other material related to Kirkpatrick's three books, numerous book reviews, and other published and unpublished writing. Most of the material related to Kirkpatrick's books consists of correspondence, book reviews, and administrative material, rather than drafts of the actual works. Text and drafts of shorter articles and Encyclopedia Britannica entries are included, however. The majority of the material in the series was written during Kirkpatrick's time as a political science professor at Brown University, and concerns foreign policy and intelligence subjects.
