I noticed Ben Witherington III had a post on his blog concerning Cambridge University Press, so I took the opportunity to ask him about the New Cambridge Bible Commentary, as well as some of his other Cambridge published works, and if he could put in a good word to get them into Logos. He answered very quickly! The post is here. It may not do anything, but he is an editor for the commentary series, as well as a world renowned scholar, so it doesn't hurt to ask!
