While Debs did not leave a collection of papers to a university library, the pamphlet collection which he and his brother amassed is held by Indiana State University in Terre Haute. The scholar Bernard Brommel, author of a 1978 biography of Debs, has donated his biographical research materials to the Newberry Library in Chicago, where they are open to researchers. The original manuscript of Debs' book "Walls and Bars", with handwritten amendments, presumably by Debs, is held in the Thomas J. Morgan Papers in the Special Collections department of the University of Chicago Library.
