The most mind-numbing part of planning an academic conference is regularization. If the session title refers to "Boethius's De consolatione," then the paper titles can't refer to "Boethius' De Consolatione." If one paper in a session is about "Hugh of Saint Victor," then the following paper can't be about "Hugh of St. Victor" or "Hugues de Saint-Victor."
They seem like tiny details, but if you skip them, the whole program looks unprofessional... so then you gotta rinse and repeat for 500 more sessions.
