The Books and Resources in the subscription packages are extremely underwhelming. I see little that would add much value in terms of books.
To be fair, I have been buying Logos books since 1991. I have gradually and consistently built a Logos library of over 9,800 books. There is little of interest to me in libraries included with the various subscriptions. I have most of the commentaries and resources that would interest me.
There are many resources that I wish were available for purchase in Logos. It seems the Logos has little interest in publishing them for my Bible software. (As always, the "Bicentennial Edition of John Wesley's Works" comes to my mind.)
With 25,000 or so subscriptions, perhaps the problem is with me, not Logos. I wonder how many people have bought previous Logos upgrades.
Obviously, this upgrade is all about features. I am more about books and resources.
