The subject files subseries consists of material related to a variety of subjects in Baker's life after government. The subseries includes brief correspondence from George H.W. Bush, Gerald Ford, John Major, and Nancy Reagan, as well as a folder devoted to Rice University which contains information about Baker's grandfather's role in the development of the University.

This subseries includes slides and negatives documenting Candela's work that he arranged by medium type and kept separately from the photographic materials included in his conceptual files. The largest group of slides follows an original numerical order that corresponds to an accompanying inventory, which can be found in Box 8, Folder 20. Researchers should consult this inventory when searching the numerical slides for images of specific buildings. Although most slide sheets include pictures of several different buildings, their original order was maintained to preserve context. Also present are slides that Candela kept by topic, arranged alphabetically, as well as a group of photographic negatives of works by Candela and microfilmed copies of technical articles on various structural engineering concepts. Slides are primarily in color and often individually marked with their location, while negatives are mainly in black-and-white and occasionally in color. Negatives were often unmarked with any identifying information, although this information was preserved when it existed. While most slides and negatives were sleeved in archival preservers, a group of unsorted negatives that were too curled to be unrolled safely were stored separately in small bags within an artifact box. A small amount of nitrate film was segregated for cold storage.

The Unpublished Works subseries is composed of drafts and notes for writings which Kennan did not publish, including lectures, addresses, articles, essays, and television and radio interviews. Significant subjects include Russian history and diplomacy, United States foreign policy, the international situation at various points in history, the fields of diplomacy and politics, the Cold War (especially its origins), and Yugoslavia from the period when he was U.S. ambassador.

The Administrative Material subseries includes agendas and minutes of the association's meetings, financial reports of the organization, and records of membership drives and copies of the organization's constitution. Also included are notices, catalogues and reviews of events the group sponsored such as exhibitions, contests, award ceremonies and galas. Also correspondence documenting the group's interactions with the University and individual benefactors.
