I purchased the NICOT/NT collection when it was originally released by Logos. It has 40 volumes. The updated has 44 volumes. Now with the collection split up, I can't figure out what volumes I don't have. I know I need Hosea and the upgrade has newer books by different scholars, but is that all I am missing. It's difficult to tell with all the different collections, but I think I am only missing 4 volumes.
