Logos used to have community pricing for older books that they sold in large collections.
Logos lost interest in the program and discontinued it. Now the collections are being sold as regular prepubs, but all the information on the individual books is missing, so the only information a potential buyer will see is the book title. Not even the authors.
Here is one example.
Classic Commentaries and Studies on Genesis Upgrade (25 vols.) | Logos Bible Software
I called and explained that nobody is going to spend $200 for a set of books only by the titles. I was told that these are prepubs and they don't have any more information. They certainly did in the past. And these books are all public domain, so they definitely have hard copies on hand.
In the past, I have submitted long lists of books I wanted to see Logos put out, and I discovered that many of them were buried in community pricing. Now it seems they will never get out.
