OXYRHYNCHUS PAPYRI: useless to the laymen because there are almost no translations of any of the papyri. The anti-religious bias of the authors seeps out of every page in that they call New Testament fragments, "religious" texts so you cannot easily find them without looking at all 15 volumes. Then, no translations. Only about 8 plates per book, many of them very poor or in black and white. Very disappointed. Got a refund.
