Once the lending period for a Kindle Book ends, it will expire and automatically return to your library (you can also return it early if you'd like). Expired Kindle Books still appear on your Kindle device or reading app, but can't be opened. You can remove them from your Kindle device or reading app using these steps:
- On Amazon's website, go to your "Manage Your Content and Devices" page.
- In the "Your Content" list, select the boxes next to the book(s) you'd like to remove.
- Select Delete.
- Select Yes, delete permanently to confirm.
This permanently deletes the book(s) from your Amazon account. They will be removed from your Kindle device or reading app the next time you sync.
