Audiobooks Purchased From Apple Can Now Be Re-Downloaded Through iCloud
According to a support document on downloading past purchases, the change was made on March 3. Prior to that date, audiobooks could not be re-downloaded through iCloud and were only available if they were included in a backup made on a Mac or PC.
A second support document outlining which iTunes purchases can be downloaded again by country has also been updated to reflect the change. In 22 countries, including the United States, Australia, New Zealand, Japan, Canada, and much of Europe, purchased audiobooks can be accessed at any time through a user's Purchased history.
In iOS 9.3, audiobooks are also available to be automatically downloaded to all iOS devices when purchased. In the Settings app under iTunes & App Store, "Books & Audiobooks" is now an option under Automatic Downloads. Previously, this section listed only books, leaving out audiobooks.
iOS 9.3 will also streamline the iBooks "Purchased" tab with deeper organizational options that sort books by category and it enables Family Sharing for audiobooks.
Apple has been gradually improving support for its selection of audiobooks. In iOS 8.4, audiobooks became available to purchase and listen to through the iBooks app, making them much more accessible. Prior to that date, audiobooks had to be purchased through the iTunes store and listened to using the Music app.
Audiobooks can be re-downloaded on all iOS devices immediately. Automatic Downloads of audiobooks will be enabled with iOS 9.3, set to be released to the public in the near future.
