These records are primarily documents that were created for and during the meetings of the Capital Area Rail Council. They include agendas, minutes, correspondence and other communications, legal documents, and drawings for railway station upgrades. In addition, there are several files that describe the history of the council. The collection also contains numerous electronic files, many of which were also included in paper format.

This collection contains twenty small notebooks that are filled with Darlington's handwritten notes. All of the notebooks relate back to Darlington's expeditions, interests, publication notes, Michigan history, and Botany 314 class. Included are notes related to Dr. Beal's seed viability experiment from 1930 and 1940.

One notebook is restricted until 2055, because it contains student grades.

The Ryan Claytor papers consist of several examples of Claytor's creative evolution ranging from an early class paper on the history of comics to drafts and pre-print proofs of his celebrated autobiographical comic series "And Then One Day."
