Logos could use a modern variation of apocryphal NT writings to accompany Charlesworth's Pseudepigrapha. I have a hardcover from JK Elliot, printed by Oxford in the 80s, called the Apocryphal New Testament (the same name as MR James' classic. This was intended as an update). It's only in softcover now (ISBN: 9780198261810), but it seems to be the same book. Either way, I would recommend getting this.
