I was having issues with covers! The I synced it again, going from library to library, and they almost all showed up. I was happy about that! CC works way better than I ever thought it could. With CC, I can adjust my tags in Calibre, and then sync my Nook with CC, and my tags show up instantly! And it doesn't mess with my Kobo Shelves. Perfection!
