The collection was originally arranged by name of the individual gathering the material. This arrangement has been retained as much as possible. These people are Leonard "Deac" Ellis, (11 February 1892 - 25 May 1979); James Ten Broek (8 September 1892 - ?); Gerald LaBelle (10 October 1899 - 30 July 1979) and Vernie Zahm (2 November 1891 - 23 August 1982). The collection contains diaries, memorabilia, newsletters, news clippings, correspondence and taped interviews. The collection also contains photographs, 1918-66, which present a variety of images from World War I at Camp Custer and in France and the annual reunions. Some of the negatives have been matched to photos within the collection, others are arranged by description. Also in the collection is a series of postcards, ca.1917-19, n.d., with images of France and the U.S. during WWI. The scrapbook series contains news clippings of WWI and reunion memorabilia.
