It's easy to send books downloaded from Project Gutenberg or other web sites to Calibre and then send them to my Kindle 3. But, when I use Amazon's "one click Whisperjet" to send ebooks directly to my Kindle -- especially when I am away from my home computer -- how do I later add them to my Calibre library so that they appear in the main library window with a green check mark that indicates each book is in the main library of the device. Do I add books from a directory (and the directory I choose would be the Kindle)? I've been able to get the books to show up on Calibre as in the main library of the device, but I have to send the book to the device (even though it's already on it) and wind up with two copies of the book on the Kindle. Other than this one thing that has me confused, Calibre works great! Advice please!
