The 75th anniversary sub-series contains correspondence, exhibit material, historical compilations used to create exhibits, newspaper clippings, programs, invitations, guest lists, meeting minutes from the historical committee, agendas and notes from Tuberculosis events and other 75th anniversary related events, and collected material found elsewhere in the collection, collated to craft a robust presentation for the event. There are also copies of press releases and press received from hosting the event. Some diary entries of Jane Skillen, M.D. are also in this collection (box 97).
