This collection primarily documents the work and ministry of the Evangelical Church's annual conferences and local churches from the middle nineteenth century to the middle twentieth century. To a lesser degree there are records that reflect the ministry of the general church as well. There are other records that pertain to filial denominations such as the Evangelical Association, United Evangelical Church, Church of the United Brethren in Christ (United Brethren Church), and the Evangelical United Brethren Churches are also found in this collection. Leedy was an avid collector of church related information so that the topical landscape of this collection is broad enough to cover information ranging from local church ministries and histories to denominational theological beliefs and social concerns. Most of the paper records center on church work in the Ohio region though not to the exclusion of other geographic areas within the continental United States and Germany. All in all this collection provides a nice overview of the diversified life within the Evangelical tradition and is an excellent resource for those who wish to understand more fully the Evangelical Church's historical influence within the ongoing traditions of United Methodism.

The Eben Samuel Johnson Collection is primarily composed of the Bishop' s papers but also includes records from his immediate family as well. The collection does not end with the death of the Bishop. It continues with correspondence between Sarah Tilsley Johnson and her children, especially with Samuel Darlow. The collection reflects the close interconnected relationships within the Johnson family. These were individuals whose characteristics were unique to themselves yet found a commonality within their love for each other and the church.

There are a total of nine series which cover a variety of subjects and record types. Included are correspondence, a journal, various writings, clippings, biographical material, and a racoon coat. Topics embrace David Livingstone, various church organizations, mission work, cultural anthropology, educational institutions, industry, cannibalism, governments, sermons, world events, etc. Much of Johnson's autographs are written in Pitman shorthand.
