Regarding The Lost Spurgeon Sermons (7 vols), I expected those resources to be discoverable in the Sermon section of the various guides. However a random check indicates that they are not. I reviewed the product page and saw no reason to expect that they would behave differently than the Met Tab or New Park sermons. (There is a vestigial note about Vol 1 being an epub, but that's no longer true.) All seven volumes are Logos Research editions and five are of Sermon type.
If the expected behavior is a work-in-progress, it would be helpful for that to be noted on the product page (maybe I missed it; it happens). I obtained them in a dynamically-priced base package, but if someone pays the hefty list price and expects sermon functionality, they might be really chapped.
I searched for another thread about this, but was unable to find one.
[EDIT] These resources appear in the Sermon Outlines section of guides.
