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 collection spans the years 1805-1928, with most of the material dating from before Fifield's death in 1859. The bulk of the material consists of letters, sermons and various documents. It also includes oil portraits and daguerreotypes of Fifiled and his wife, Celia. A few of the sermons date from Fifield's years as a secular banker; this indicates that he probably continued to preach somewhat during those years. It should be noted that several of Fifield's sermons are written on the back of correspondence which he received. Many of the documents are in poor condition and should be handled carefully, as should the oil paintings which are both cracked and flaking.
