Please forgive me if this has been asked before - this is my first post. I love Calibre, but how do I copy new books from my Kindle into Calibre? On the Amazon page it gives me a choice to send new book purchases to my Kindle, but when I ask Calibre to add new books, it shows me the list of books and documents on my Kindle with unrecognizable names. And it doesn't even have the right date so I could sort on that. Please help! Thanks!
