For some people, kindle has become more than an option, I use it daily to read articles, especially longer ones. With Amazon-provided “send to Kindle” extension in Chrome browser, sending documents to Kindle devices has become very useful.
But Kindle digital library has a very poor management function, while you can delete one single article, but you cannot delete several articles at once. That is why you have gone a long way to here.
In Chrome browser, get to the page where you the list of documents you want to delete from Kindle digital library, press “ctrl + shit + j”, a developer’s tool will pop-up. Select the console tab, and paste following lines of code, and press enter.
Then you will see following screen that shows deleting action.
