I have books on this tablet. I have them in Nook (in its own library), in Kindle (in its own library), in Calibre, and in OverDrive (in its own library). In addition there’s a “My Library” folder on the Android 4.4 home screen with half a dozen books in it.

How the heck do you merge, copy, move, or otherwise consolidate these things into one big folder, whether it’s called My Library or not?
