For instance, Zondervan Illustrated Bible Backgrounds used to be available as a full set with al volumes both OT and NT. That is no longer available. The full OT set is by itself buy vol 2 (of a 4 volumes) from the NT set can no longer be purchased.
The assumption being that somehow Logos lost the license. So, if someone bought that book or the entire series years ago before vol 2 disappeared would they still be able to download it say in the case where they do a new install on a new computer?
This seems like a very big problem if you could no longer access and download it...
