The Geraldine K. Barnes papers consist of textual paper documents and paper-back books. The Personal Papers series comprises Box 1 of the collection, and contains biographical information, faculty reports, correspondence, and Division of Girls and Women's Sports (DGWS) administrative materials. The series, "Division of Girls and Women's Sports," comprising five boxes of the collection, contains paperback rule books pertaining to the various sports Barnes was involved with at Eastern Michigan University and were used for instruction and coaching purposes when much of the male and female faculty in the Department of Health, Physical Education, Recreation and Dance (HPERD) were also responsible for coaching competitive athletics. These books provide insight into Barnes' time and work regimen at Eastern Michigan while simultaneously shedding light on the value of physical education in the early to mid-19th Century, the era in which the rulebooks were produced. Although not a complete picture of Barnes' tenure on faculty, her collection of rule books provides insight into the diversity of responsibility placed on the teaching faculty in the Department of HPERD.
