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.

This collection of personal papers of Mildred Anne Paine includes 23 diaries and journals, photographic images, correspondence, clippings, and biographical miscellany, most of which concern her years of missionary work. The correspondence includes personal, business, and Dear Friends letters.

Most of the diaries contain additional related information tucked between the pages, including letters, poems, prayers and newspaper clippings. The completeness of entries varies from year to year, with the most detailed and personal information from 1957-1974. Some years are missing from this collection, particularly in the period of 1926-1943. The entries are generally written in reflection of the day at hand, noting activities both personal and missionary related, daily concerns and observations, and interactions with colleagues, staff, family, and friends.

This collection also contains genealogical information, including a hand-inscribed book of births, deaths, and marriages dating from 1830, created by Paine’s Aunt, Rena W. Goldsmith. Additionally, Paine kept a birthday book of friends and family dating from 1914.

There are eight audio cassettes of Bishop Arthur James Armstrong teaching Bible themed topics at an unidentified meeting or retreat in 1977.
