Here is a fascinating video of Ludwig Koenen, one of the giants in the field of papyrology. He talks about his own training, his training of his own graduate students and the method thereof, his work on the Cologne Mani codex, and the future of papyrology. The video offers an excellent insight into the history of papyrology through the words of one of its doyens.
Thanks to Michigan for producing this. The Michigan collection and the faculty and staff there are simply the best. If I could move to Ann Arbor, I would!
