Most of the material in this subseries documents writing topics Kimball intended to address but never developed beyond the briefest notations or outlines, including a bibliography of his own published writings. Several writings are more fully developed, but their publication venue unclear, such as his discussion of the elements from the Chateau de Cussac given to the Philadelphia Museum of Art in 1928. Earlier writings include what appears to be Kimball's rebuttal to an article disparaging the architecture of Harvard University as well as a few poems. The file completing this subseries also sums up Kimball's passion for writing. Jotted down on a slip of paper, Kimball's to-do list for the Summer of 1934 consisted of revising three writings, finishing another, preparing a related work and noting a few other possible topics.
