The collection consists of correspondence and miscellaneous items primarily related to Dennis's professional life.

Outgoing letters are from the mid-to-late 1920s, and incoming letters are primarily from the early-to-mid 1920s. The topics are mostly related to the Chicago Daily News, the activities of the journalists and foreign correspondents, and the administration of the paper (relations with newspaper syndicates and other papers, for example). Notable correspondents include George Ade, Ray Stannard Baker, Eugene Field, Henry Blake Fuller, Victor Lawson, John T. McCutcheon, Hiram K. Moderwell, Edgar Mowrer, Paul Scott Mowrer, Hal O'Flaherty, Wallace Rice, Walter Robb, Graham Taylor, LeRoy T. Vernon, and Junius B. Wood. Foreign correspondents during this time reported back on major world events, such as the Spanish-American War (in both the Caribbean and in the Philippines), and various political campaigns in Europe, India, and Japan.

The subject files consist of items relating to the Chicago Daily News, including its sale in 1925, works by Dennis, and material relating to Eugene Field, including checklists of books by and about him. There are a few photographs in the final series of the collection.
