This collection represents what can only be a portion of items from Kerr's personal files. They consist mainly of correspondence, but also include some diaries and writings, ledgers, class records and even Kerr's 1879 traveling papers for his stay in Japan. The bulk of the material is correspondence, which is both personal and related to his work at the university. Some of the letters chronicle his dismissal from the university, which is an integral part of the early history of South Dakota State University.
