The EP Study Commentary is on pre-pub and is going to be released on November 28th.
It's missing a couple volumes:
Isaiah, vol 2, by John L. Mackay (2009)
1 Kings, by John A. Davies (2012)
I feel like it is false advertising to say "With the Logos Bible Software edition, you have instant access to ALL twenty-two volumes of this important commentary series." Granted, 1 Kings just came out, but Isaiah vol. 2 has been out a while, and the set includes books released in 2010 and 2011.
