Today Logos put the Augsburg Commentary on the New Testament on prepublication. This includes the Galatians commentary of Edgar Krentz. This is quite a short commentary, combined as it is with commentaries on three other biblical books written by two other authors.

Logos also released a collection of SIL exegetical summaries which includes a volume on Galatians by Robert Stutzman. This is an interesting series which presents exegetical summaries taken from numerous commentaries. It provides a way to gain a quick overview of how various commentaries have concluded their exegetical work. This looks like a very valuable resource for those who own a lot of commentaries in Logos because they can look up the passage in SIL and then open up their commentaries for more detailed information.
