Make this automatic with the help of Tampermonkey browser plugin:

Step 1: Install Tampermonkey

Tampermonkey is a browser extension that allows you to run custom JavaScript on websites.

🔗 Install Tampermonkey:

Google Chrome: Tampermonkey Chrome Extension
Mozilla Firefox: Tampermonkey Firefox Add-on
Microsoft Edge: Tampermonkey Edge Extension

Step 2: Add the Script to Tampermonkey

Click on the Tampermonkey icon in your browser.
Select "Create a new script".
Delete the default template code.
Copy and paste the script below into the editor:
Click File > Save (or Ctrl + S / Cmd + S on Mac).
Close the Tampermonkey editor.

Step 3: Open Your Amazon Content Library

Go to Amazon Content Library
👉 https://www.amazon.com/hz/mycd/digital-console/contentlist/booksAll/dateDsc/
Manually navigate to the page number where you left off.
Example: If you've already processed page 1, go to: 👉 https://www.amazon.com/hz/mycd/digital-console/contentlist/booksAll/dateDsc/?pageNumber=2

Step 4: Start the Script

Once you are on your starting page, the script will automatically run.
It will download books on the current page.
After finishing, it will automatically navigate to the next page.
It will continue running until page 168 (or the last page with books).
The script stops automatically when there are no more pages left.

Please note that this works best if you only have one kindle device registered to your account. My recommendation is to remove the other kindle devices from your account until you only have your default device, then run the script. After you are finished, you can re-register your other devices.
