The Dodge H. Dean World War II Collection consists primarily of training materials from Dean's service with both the Royal Canadian Air Force and the U.S. Army Air Forces during World War II.

Training materials from Dean's time with the Royal Canadian Air Force (RCAF) from about 1937-1942 make up the bulk of the collection. Included are printed lecture outlines and printed notes on a variety of topics such as airframes; airmanship; airways regulations; armament; engines; instrument training with a Link trainer; instrument flying; maintenance; meteorology; and navigation. Many of the documents include diagrams and some have handwritten annotations. Some documents have the name of "Sgt./Pilot Jarred, A." written on them; his relationship with Dean is unknown. Some of the documents are specific to the RCAF station in Trenton, Ontario. There is also a notebook of Dean's handwritten notes; an examination and syllabus on navigation are tucked into the notebook.

Dean's service with the U.S. Army Air Forces (USAAF) is documented as well, though with fewer materials. Present are memos from the Department of Training at Hendricks Field in Florida; handwritten notes; a Flying Regulations booklet from Moody Field, Georgia; and a variety of bulletins and memos from the flying school at Moody Field. All these materials date to 1942.

A small day-book style calendar from 1950 is present but has been used more like a scrapbook. It includes clippings documenting Dean's military career from about 1937-1943; a few handwritten notes; and three small black-and-white photographs. The photos depict his family's house on Wellesley Avenue in Spokane, Washington; a snapshot of him; and a snapshot of a woman who is likely his mother. The book was possibly put together by his mother. The majority of pages are blank.

Any military service or other flying experiences of Dean's post-World War II are not documented in the collection.
