It's that time of the year when we are working on processing the new D.Min. theses. A quick query of our catalog turned up one thesis title from 2001 that was 207 characters long:
Development of an educational program of Christian formation for the Baptist Church of Quintana, Hato Rey, Puerto Rico to deal with the racial and ethnic prejudice in the congregation and the local community
What's the longest thesis title in your library? To be sporting, I'll allow Ph.D. titles as well.
