'The aim of this volume is, firstly, to provide as accurate as possible, an edition of the relevant papyrus texts. Secondly, to consider the latter vis-a-vis the text as handed down in the manuscripts. For that reason unidentified scraps are not included: they will be found in the original editions referred to. The lists that contain the evidence do so in a condensed form and should be used in conjunction with the transcripts of the texts and with the commentary. References are only given where necessary.' (A.H.R.E. PAAP, p.VII).
