On my last mac system I used iTunes for syncing some PDFs and other books to my ipad. Now on my new MBP with Mavericks and iTunes 11 there is no Books library anymore, but a new iBooks app.
I started to add some files to iBooks on my mac and followed the instructions to sync them to my ipad, but when opening iTunes and clicking the Books sync section, I still see only the old books formerly added to iTunes in the list. No new book from iBooks is being shown, so not synced to iPad.
I even don’t see a way to delete my old content (and move it to iBooks), because there is no library anymore. Just deleting the Books folder under iTunes Library didn’t work - the Books sync section still shows the old content, although the sync now complains that it can’t find the files. (Deleting Cache files didn't work here)
So how can I actually enable iBooks app content sync from Mac to iPad and get rid of my former iTunes books library?
