So I clicked on "add a new edition" link. The new window show me the data of the original book already filled, so I add the rest, including the photo cover.
Editions have been combined! The "add a new edition" link works almost the same way as "add a new book", except with helping you prefill some fields like title and author. Editions need to be manually combined by a librarian.
Y try to add a new edition of this book:

The result looks like if I add a complete new book:
https://www.goodreads.com/book/show/1...
BTW: The ISBN13 is the same (9788475222141)
Thank you for the help.
