Correspondence
Correspondence (1909-1973) is the largest series in the collection. It is arranged alphabetically, and includes both incoming and outgoing correspondence. The correspondence from the 1930s and 1940s contains lengthy critical and philosophical exchanges with important American anarchists such as Henry Cohen, Steven Byinton, and Marcus Graham. On more personal matters, Labadie corresponded with Theodore Schroeder and John Scott. The correspondence with Agnes Inglis is interesting for its documentation of the early years of the Labadie Collection at the University of Michigan Graduate Library. Inglis frequently wrote to Labadie informing him about the researchers using the Collection, as well as about new acquisitions. It was through her that Labadie met James J. Martin, who later published a collection of Labadie's essays. Labadie's correspondence with Mildred Loomis spans the longest period of time, from 1947 to 1971. Important correspondence in the 1960s include Herbert Roseman and Don Werkheiser, whom Labadie met through the School of Living.
