Berlin (dpa) – Users of iBooks, Apple’s ebook reader, likely signed up for the service because they felt they could do without physical books. But the plan was never for the works to disappear entirely.
That’s the problem some Apple customers have reported of late. They say that if the app is not used for a period of weeks and the device is disconnected from the internet, the digital works sometimes vanish from the app’s shelves.
The reason? The ebooks have digital signatures that must regularly be compared with those on file with Apple’s servers. If that does not happen often enough, the digital books cease to be.
To prevent the problem, regularly open the app while connected online.
This step is of special importance when one is travelling and might really want a good book.
