MORE INFO ON THE MANUSCRIPTS found with the Coptic Gospel of Judas has been published on the rather wild website of Michael van Rijn. (Scroll down to "The Ferrini Files"; van Rijn doesn't seem to do permalinks.) I have no way of verifying this information myself. Roger Pearse notes the post on the Textual Criticism list and he has also published the relevant documents on his own Tertullian Project website. In his TC message he summarizes:

The others are a Greek Exodus, which now seems to have been chopped up and scattered; a Sahidic letters of Paul (now revealed to also contain parts of Galatians), the whereabouts of which are almost completely unknown; and a Greek mathematical treatise cut up into at least chunks (and probably more: we now know of at least 5 pages unaccounted for).

If all this is accurate, it is a sad fate indeed for these manuscripts.
