I have just replaced my iPad as the old one was irreparably damaged, I had a lot of PDFs on iBooks is there any way to get them back, I think they were saved under my email address. Can anyone help please.
If the iPad was backed up to iCloud or to a Mac recently you should be able to recover from the backup.
If they were put on there from the Mac and you did not delete them from the Mac then you should be able to put them back.
If they were purchased from the App Store some how, then you should be able to reinstall them from whatever app you bought them with.
If the only place you had them was on the iPad and it will not turn on or you can not connect to a Mac to back it up, then whatever was on that iPad is gone.
