Kindle, Amazon’s e-reading app, is similar to Apple’s iBooks. You can store e-books and PDFs from the cloud on your device, download book samples via the Book Browser, and read to your heart’s content. In the Kindle app, you have a Library with all of your books. Book samples you've downloaded can be deleted, but old books or PDFs kept in the cloud must be archived. Here’s how to remove books you’ve read from your iPhone or iPad.
Books and PDFs that are stored in the cloud and available via your Kindle app cannot be deleted. They can, however, be archived which means it returns to the cloud and is removed from your device. To delete a sample or archive a book, open the Kindle app and navigate to your Library. At the bottom, select Device.
If you’re viewing your items in list mode, archive a book or delete a sample by swiping left and selecting either Delete (samples) or Archive (purchased books).
If you’re viewing your items in grid mode, tap and hold to see your options such as Delete Permanently (samples) or Remove from Device (purchased books).
