The message is a product of device/library book matching.
A book on the device is matched against a book in the library if:
- The device book's UUID (unique calibre ID) matches library book's UUID. This match ignores title, author, and any other metadata.
- The device book's title and author(s) match a book in the library.
- THe device book's title matches a book in the library, and the stored calibre database ID for the device book matches the same book in the library.
Your next question is probably "How do I get duplicates?" The normal way is by changing metadata and sending the book to the device again. Changing metadata for a book does not change its UUID. For example, assume you have a book in your library with the title 'Metadata Rocks', by Calibre. You send it to your device. The file name of the book will depend on the save template, which probably has both author and title in it. Next you decide to change the title to 'The Rocking of Metadata', and send it to your device. The file name will almost certainly be different, because the title is different. You now have two books with the same UUID on your device.
Theducks provided you with a method to list those books. On the library view, right-click on a book and choose Remove Books, then Remove matching books from device. You will be presented with a list of matching books. There is no requirement that you actually delete them.
