Consider if there's a topic related to DePauw's current or historical policies, practices, etc. The University Archives (lower level of Roy - across from Café Roy) has a wealth of resources, including physical items (example: old course catalogs) and digital items (example: old issues of The DePauw).
If you are interested in going this route, plan ahead to spend time during their open hours, and schedule an appointment with Bethany Fiechter.
