Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
AS Chapter 12 EXPLAINS, iTunes is the traditional conduit for moving files between your computer and your iPad. True, you can always pluck a new copy out of the iCloud if needed or have the book automatically download over the air (Use iTunes in the Cloud). But what if you don’t have an Internet connection at the time or don’t want to use iCloud for whatever reason?
You can still back up your books to your computer by syncing your ’Pad with iTunes. And no matter how you copy your iPad’s contents, backups make for a much less stomach-churning event if you have to restore the tablet’s software (Start Over: Restore Your iPad’s Software) or if you accidentally delete a book you weren’t quite done with.
