As a Logos Connect subscriber, my desktop has updated to Logos 9. I certainly understand how difficult it can be to really categorize commentaries by denominational perspective. I also appreciate that you have started to do this task, and include this as a way of organizing commentaries in the Passage Guide.
In doing a few sample passage guides, it did pick out Luther's exegetical writings and the Augsburg Commentaries - a good start. But it did not pick up Lenski and The Lutheran Commentary on the New Testament passage I tried, and did not pick up K&D and Leupold for the Old Testament passage I tried.
Even worse, it listed Richard D. Nelson's volume on Kings as being a Methodist commentary. He may work at a Methodist school, but is on the ELCA clergy roster.
I understand that this is a new feature, and I expect more tagging will come. But the mistaken tagging is especially concerning.
