Branch of the YMCA; Annual reports, clippings, correspondence, financial records, minutes of meetings, photographs, press releases, published materials, rosters, and scrapbooks; also includes collected branch records for the Railroad branch, 1877-1890, and the Downtown branch, 1890-1909; and publication, Detroit Young Men, 1911-1922.

The records of the Metropolitan Offices of the YMCA of Metropolitan Detroit consist of annual reports, correspondence, financial materials, minutes (Secretary's records), photographs, published brochures and pamphlets, and scrapbooks. The materials document, somewhat unevenly, the efforts of the YMCA to tend to the spiritual, physical, and social needs of the young men in Detroit. The strengths of this record group are in its minutes (Secretary's records) and photographs, each of which provides detailed and telling insight into the development of Detroit and the YMCA from the nineteenth century to 2006. The scrapbooks created by the YMCA, 1936-1973, are also of interest in that they accurately reflect all newspaper coverage of YMCA events and activities for this decade.

The records have been arranged in four series: Administration, Secretary's Records, Visual Materials, and Scrapbooks.
