I had the "pleasure" of working on some of these texts during my graduate studies. Since then, I've come to recommend anyone who can get access to the texts do so.
This edition promises to provide the original text accompanied by fresh English translations.
So, what is the significance?
Simply put, these texts flesh out the actual context of the early Church until approximately the fifth century.
While it is easy enough to disembody early Christianity and spiritualize what the early Church must have been like, this collection adds a concrete quality to the early Church. In a world full of ecclesiastical conceptions born from the narrow witness of the New Testament and Patristics, in which it has been possible to create an almost dualist ecclesiology, the Oxyrhynchus provides "the rest of the story," as Paul Harvey would say. This is your glimpse into the life on the ground of the early Church, particularly as it was in Egypt.
