title_body: How can you delete the books from 'Cloud' in Kindle PaperWhite?
upvoted_answer: Aha, I figured it out. You need to log in to your amazon account from a PC or laptop. 
  
  
  Go to MANAGE YOUR CONTENT AND DEVICES on amazon.com 
  Select MANAGE YOUR CONTENT.
  For the dropdown labeled SHOW, change it from BOOKS to DOCS.
  
  
  From there, you will see all your personal content and be able to delete content.
