According to Merle Chamberlain, the archivist who first processed the Fiske Kimball Papers in 1982, "Kimball's papers were found, helter-skelter, in a loft storeroom of the Museum. File drawers had been transferred carelessly into open boxes and other containers without identification....It was apparent that the Kimball papers had been shifted from pillar to post for twenty years after coming to the Museum. Even in 1975, they were not secure. A flood from the newly installed air-conditioning equipment soaked some of the boxes and produced mold. The papers were salvaged and moved to the present Archives...." The papers were initially processed into 19 series.
The current arrangement consolidates the collection into eight series, five of which focus on aspects of Kimball's professional life: "Architectural projects," "Historic preservation projects," "Art historical and historical projects," "Teaching positions," and "Writings and research." Of the remaining series, "General correspondence and related material" and "Personal papers and records" document multiple aspects of Kimball's life. "Reference material" consists of a mix of documentation Kimball used for multiple purposes.
