I had iBooks on my iPod touch 4th generation and I removed the app but the books keep appearing in my iTunes library. I've tried deleting them but they keep coming back and I tried to unsync them but its not working. I wonder why it keeps adding them books even though I don't have the app anymore. I would appreciate someones help on this because I am deeply frustrated. By the way, the books were free if that means anything. And I also tried restoring my settings but that dint work either.
