I'm trialling Logos 8 using Connect Essentials and my existing Logos 7 Gold library. I'm finding the Theology Guide a bit hit and miss. Have you tried it, yet?
For example, some subjects I've looked up do not link to resources I own when I think they should have, while others do.
Sometimes it links to relevant bits in Calvin's Institutes, but not other times, when there would have been plenty to draw from.
How are you finding it?
