The papers consist of clippings, published transcripts, typed transcripts, reports, correspondence, memoranda, publications, and pamphlets pertaining to the merger of the Evangelical United Brethren Church and the Methodist Church. Additional extensive material relates to Bishop Oxnam's hearing before the House of Representatives Committee on Un-American Activities, as well as the Committee on Inter-Jurisdictional Relations.
The first series is comprised of correspondence, the bulk of which relates to the Inter-Jurisdictional Commission of the Methodist Church. The work focused on the dissolution of the Central Jurisdiction and the merger of the Evangelical United Brethren and the Methodist Churches. Some of this correspondence is of minor importance, but much of it reflects opinion and counter opinion and proposals growing out of the subjects under consideration.
The second series is the major part of the collection and includes all the substantive minutes, reports, and legislative proposals which emerged from the work of the Commission on Inter-Jurisdictional Relations. This material is international in scope.
The third series is a two volume collection of Parlin’s speeches and addresses given to churches, schools, universities and business groups. These volumes have been dissembled and organized in chronological order.
The fourth series is biographical in nature in so far as it includes articles, clippings, and statements reflecting Parlin's wide and varied projects and interests.
The fifth series is a Book of Remembrance from the Drew University Collection. These letters and statements of appreciation honor Parlin's achievements and contributions to the life of the church.
The sixth series is a substantial collection of articles, clippings and most importantly working documents regarding the hearings of Bishop G. Bromley Oxnam before the U.S. House Un-American Activities. Parlin served as Oxnam’s counsel and strategist at these hearings.
