title_body: Can't find books I have bought
upvoted_answer: Go to Manage your content and devices and verify that these ebooks are listed. If you have uploaded content instead of purchasing them, I may have to change the dropdown  from Books to Docs. 
  
  Piece of advice. Create collections to categorize your ebooks -- (History, Fiction, etc). When in collection view, you can see uploaded ebooks and purchased ebooks together. 
  
  On my android device, the kindle app lets me see all ebooks I have purchased and uploaded. If the cover image icon doesn't have a check, that means it exists only on the cloud, and you must download it separately for this device.
