I recently reformatted my Mac, and in my haste I backed up the wrong iTunes folder. Music I'm not too fussed about, because I have very little that wasn't purchased from iTunes. Same with Apps, I can simply 'transfer purchases' from the iPad and everything is there in iTunes. However, I can't find a way of getting my iBooks PDFs back into iTunes. I have around 15Gb worth of PDFs that I have added to iBooks after downloading from websites, emails and previously added through iTunes. The only possible solution I'm aware of is via a Jailbreak, which I'd much rather not do. Is there another way of doing this that I'm not aware of?
