I am a touch confused.
I just noticed that I have both LLS:9781433542558 and LLS:JPCKRNVNGLCLLF in my library. I know not how. They appear to me to be the exact same book.
The ebook version has been updated/added to my library more recently, though the Logos Research Edition file has been updated more recently.
I would have expected to only have one of them in my library, even if the Logos Research Edition replaced the ebook at some stage.
