The Wilson Day Materials collection contains items related both to the day's original focus on seminars, concerts, and other events and to its current form as a day of community service. Materials from earlier Wilson Day celebrations (1972-1987) include letters of invitation, tickets, programs, speeches, photograph albums, and press clippings, as well as planning material such as guest lists, correspondence between guests and event organizers, and drafts of programs and letters of invitation. Early correspondence is between Chancellor W. Allen Wallis, University Relations Director Don Lyon, and Wilson Day committee members. Correspondence is also between Lyon or President Robert L. Sproull and those involved with planning Wilson Day. Letters of invitation are from President Sproull. Materials from 1990 onward consist of correspondence among organizers, service project lists, letters of invitation, T-shirts, press clippings, and photograph albums. Correspondence from 1990 onward is often written by the Associative Director of Media Relations Jan Fitzpatrick.

The Writers Workshop Collection consists of primarily of photographs taken by James S. Peck. Mr. Peck was formerly the Director of Public Relations for the Graduate School of Management (today the Simon Graduate School of Business). He had also handled public relations and promotional activities for Dean Robert Koch of the University School, which included both the Writers Workshop and the University Summer Theater. The collection also contains the annual flyers or programs for most of the years of the series.
