Series 1 contains material reflecting Robert R. Bowie's wartime duty (1942-1945), his postwar assistantship to the Deputy Military Governor for Germany, General Lucius Clay (1945-1946), and his position as Special Adviser to High Commissioner for Germany John J. McCloy (1950-1951).

Series 4 documents Bowie's activities after his government service and after his retirement from Harvard University in 1980. The series reflects Bowie's abiding interests in arms control, NATO and the Atlantic alliance.

This series includes various reports and information about particular individuals related to the global women's movement.

Personal correspondence to family and friends. These materials are not in any particular order; many letters remain in original envelopes.

The letters in Series 1: Correspondence are primarily personal in nature, though some business correspondence is also included. Most of the correspondence dates from the Birds' time living in the Middle East and India in the 1960s and 1970s, though there are also letters that predate and postdate Eugene's tenure with the Foreign Service. In addition to the Birds' outgoing letters describing their lives to family and friends, the series also contains a large portion of letters that the Birds received from their children and from other Foreign Service families.

Series 4: Writings includes the Birds' articles, poetry, speeches, and other writings on the Middle East and various topics. Most of the series is composed of Eugene Bird's writings; the majority of Jerine Bird's writings may be found in Series 2: Saudi Arabian Women Projects. Of note are Eugene Bird's notes and other writings related to an unpublished biography of the diplomat George Antonius.

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.

These records are composed of mostly correspondence and subject files that were created in the course of Ullman's work as an academic, primarily at Princeton University, and in various other positions he held during his career, such as his term on the editorial board of The New York Times. The records also include some of Ullman's published articles and what appear to be notes and research prepared for lectures on European governments and foreign policies. Of note is Ullman's correspondence with well-known individuals in the field of foreign policy, particularly George Kennan.

This portion of the collection includes correspondence, reviews, and research materials that pertain to Ullman's first published scholarly work, the three-volume Anglo-Soviet Relations, 1917-1971.

The Biographical series includes materials regarding Lotka's appointments, resumes and obituaries, correspondence, Lotka's last will and testament, census bureau information regarding his wife, Romola Beattie Lotka, and Lotka's class notes from Birmingham University.

The Professional Organizations series documents Lotka's involvement with several statistical and scientific organizations, including the American Statistical Association (ASA), the International Union for the Scientific Study of Population, and the Population Association of America (PAA). The papers include correspondence, papers, pamphlets, meeting agendas, conference information, and administrative materials for each organization. The series also includes correspondence between Lotka and other scholars discussing the organizations.
