I'd really like to see Zondervan's Dictionary of Biblical Archaeology edited by Blaiklock. It is superior in my view to the Archaeological Encyclopedia of the Holy Land currently available in Logos. I called about this when Zondervan released a bunch of titles to Logos, and was told that eventually all Zondervan titles would be offered. This is one I'd have a priority on for purchase.
I'd also like to see the Archaeological Study Bible by Zondervan released in Logos. There's a lot of great stuff in that volume that would be a lot easier to find if it were searchable.
