The bulk of the three hundred and fifty-one folders in this collection are placed in the Study of the Parish System series. In the mid-1960's, the Council of Bishops asked Bishop Garrison to do a comprehensive study on how to restructure the parish ministry to meet the rapid changes in both society and United Methodism. Here we find all the records of Garrison’s study which still influences parish ministry into the early 21st century. The researcher will be surprised at the efficiency and scope Garrison brought to the task. By the early to mid-1970's Garrison wound down his research and presented his findings to the Council of Bishops. The Episcopal series documents Bishop Garrison’s work as administrative head for both the Dakotas and Indian areas. Besides illuminating his bishopric work amongst the annual conferences within the appropriate episcopal geographic boundaries, there are other records on important topics facing the larger denomination as well. A number of audio CD’s created from reel-to-reel tapes record meetings and ordination services that Garrison took part in during his episcopal tenure. The Ministry series covers his professional life prior to his episcopal election. One will find sermons, overseas trips, vital church records where he served and other kinds of materials related to local church ministries. Lastly, is the Education series which centers on higher education. Degrees, earned or honorary, are located in various folders. Correspondence makes up the rest of the series which includes notable figures in church and political circles.
