Finding Nook ebook files on HD+

I am new to this site, so please forgive me if I have overlooked something obvious.

I have a Nook HD+ running Cyanogenmod. I believe it is rooted. I have access to files and can copy/move them by linking it via usb to my Linux computer. I am running an older version of the Nook app.

I have been looking for my Nook ebook content and found it at storage/emulated/0/Nook/Content. I am able to copy and paste most of the epub files from the Content folder to my computer, but (and here is the problem) I cannot copy all of them. The more recent books I've bought show up in the Content folder on the Nook, but they don't show up in the window on my computer. They simply are not visible in the file list on the computer.

Can anyone suggest anything? Thanks.
