The Oxyrhynchus Papyri, Part I: 1898
Grenfell and Hunt brought out the first full volume of publication of their finds at Oxyrhynchus with commendable speed in the year after the excavations, not an easy task given the then unfamiliar nature of much of what they had found. They included as the first item the Sayings of Jesus papyrus which they had published in a separate pamphlet the year before.
This was Part I of what was to become the most prolific publication series in the history of papyrology, reaching Vol.LXV in 1998. The books were designated volumes rather than parts with effect from Vol.XXXIII in 1968, the first to be published under the auspices of the British Academy.
