Papers include published materials, meeting minutes, and organizational records of three units of the Modern Woodmen of America and Koopman family papers.
The majority of the Koopman Papers focus upon the activities of the Modern Woodmen of America, particularly Camp 7660 (Falmouth, Michigan), and include correspondence, by-laws, membership certificates, catalogs, and financial records. The minutes of Camp 10399 of Butterfield are also included. Some Koopman family correspondence and miscellaneous materials complete the collection.
