This subseries consists primarily of the notes, outlines and manuscripts Kimball prepared for various lectures he gave throughout the country. Spanning a period of approximately three decades, Kimball spoke at symposiums, seminars, dedications and dinners, addressing a variety of audiences, from museum colleagues and other professionals to educators, students of art and architecture, patrons and the general public. He addressed a range of art-related topics, such as the role of art museums in education, American architecture and Philadelphia antiques. A few lectures focused on the repercussions of World War II. In these Kimball spoke of the destruction and preservation of European art as well as the importance of American museums remaining open during wartime in order to provide civilians and soldiers and sailors on leave with "spiritual refreshment." The one unidentified address written in French may date much earlier than the other material. The original folder noted that the manuscript was in Kimball's early hand, and several of the pages are on University of Illinois letterhead, which could date the document ca. 1912. No other material in Kimball's papers appears to relate to this address.
A number of Kimball's lectures have no documentation other than being noted generally in correspondence. These lectures are included in the inventory with reference to the appropriate file within the "General correspondence" series. Documentation of Kimball's lectures about the Philadelphia Museum of Art, or given there, are part of the Fiske Kimball Records. Most are filed as "Public Speaking" files within "'Publicity" subseries referenced below.
