Tommy has brought to my attention a bibliographical item with the following description:
Worrel, William H. "Fayumic Fragments of the Epistles." Societe de la Archaeologie Copte 7.
The description comes from: http://www.panikon.com/phurba/biblio.html
There are evidently quite a few problems with this bibliographical entry, including the author's name and mistakes in the French. I should be most grateful if someone would use text-critical devices or their own knowledge of the material to tell me what the publication details really should be, so that I can add it to my Coptic Bible Bibliography.
