On the Books screen, you can manage how iBooks files, PDFs, and audiobooks are synced to your iPhone.
- Sync Books - Check this box to enable the syncing of books and related files from your hard drive to your iPhone. When you check this, the other boxes below will light up and you'll be able to select individual books. Check the box next to each book to sync it.
- All/Selected Books - Check All books to automatically sync all books to your iPhone. Check Selected books to control which get synced.
- Sorting Options - Using the drop-down menus under the Books heading, you can sort files by type (Books and PDF files, Only Books, Only PDF files) and by title/author.
- If you choose Selected books, check the box next to each book you want to sync.
Below the Books section is the Audiobooks section. Syncing options for Audiobooks work the same way as for standard books.
