The collection includes chapter minutes (1911-1934) and six scrapbooks from the 1930s to the early 1950s, with a letter from Brother David Levy Reiner (Class of 2003) entrusting the scrapbooks on behalf of the chapter. The scrapbooks were compiled in part by Brother Robert Elwell (Class of 1950), and they contain pictures, clippings, and captions covering subjects such as class pictures, football and other sports, social events, pledging, and Delta Upsilon involvement at the University of Rochester.

The Delta Kappa Epsilon (Beta Phi Chapter) papers include minutes, a history of the chapter, material relating to the alumni organization, material relating to the 150th anniversary of the chapter and other events, publications, various three-dimensional objects, a songbook, scrapbook, and guest books.
