Gabe,
I found that the new "official" faithlife group links to www.logos.com/lutheran just beneath your mail addy. This of course brings up the Logos product page filtered by "Christian group" = Lutheran. It shows 140 results (most of them are Wisconsin Lutheran Journals, The People's Bible and Lenski's commentaries).
I wondered that I didn't see many Lutheran products I do own in the list, until I recognized that http://www.logos.com/products/search?q=publisher%3aconcordia has 67 results, only 8 of which are tagged as Lutheran.
As you probably are aware from your other denominational/group specific duties, the respective tagging is very often incomplete - I'd suggest to tag the Concordia-published books and bundles "Lutheran".
