The Administrative Files follow standard practice using the name of report type, originating committee, special event or external entity as the subject heading. The deepest historical contents are found in folders for Annual Reports (beginning 1944), Black Book (1945-56), Budgets (1954-56), Federation Membership (1947-51), Membership Committee (1942-47), and Organization of the Federation (1941-48). It should be noted that much financial, membership and special events information not included in these Administrative Files can be found filed with the Meeting Minutes at which the topic or report was discussed or in the Annual Reports.
Of notable length are the holdings of Annual Reports, which cover the years from 1944 - 2002 (missing are 45-46, 48-52, 53-54 and 1980). These consist of the year-end reports from the President and Executive Director; summary reports of the major standing and special events committees; and Treasurer's report and budget as presented to the Annual Assemblies. The financial reports contained therein include the past year's income and expenses including support received from each member congregation (grouped by denomination). A calendar of upcoming events for the year is also presented, as are award and scholarship recipient's names. The Annual Reports also include a full listing of nominated officers and board members for the forthcoming year containing full name and church community to which they belong. Anniversary year's reports from 1981, 1990, and 2000 include reflections, summaries and histories.
