The Don Plumb collection contains university related items collected by the EMU alumnus between 1959 and 1960. The collection is made up primarily of homecoming related materials such as T-shirts, pennants, buttons and stickers.

The Eastern Michigan University Pins and Buttons collection is comprised of Pins and Buttons that were distributed to promote causes, commemorate events and/or organizations.
