Amazon is making some big changes to its Kindle books, and you only have a few days to prepare. Here's everything you need to know before it's too late.

Amazon will remove the 'Download & Transfer via USB' option from its website. Here's how to save your collection.

Amazon confirmed the removal of the book download feature in a statement to The Verge. “Customers can continue reading books previously downloaded on their Kindle device, and access new content through the Kindle app, Kindle for web, as well as directly through Kindle devices with WiFi capability,” said Amazon spokesperson Jackie Burke.
