I don't understand how this is not available. It is by Fortress Press, which Logos works with regularly, and it is from the Hermeneia commentaries, which Logos has, so it seems that it would be an obvious addition to Logos. It would be nice to have a newer version than Charlesworth.
From the back:
"This is the most authoritative translation of 1 Enoch, based on the best critically reconstructed text, available in a convenient, portable volume. A very useful book" (John J. Collins).
