**Do nothing.** When you create a contract with a traditional publisher, they will tell you what to do. Almost certainly they'll want to use their own ISBNs. As for the ISBN itself, it's done with. > [Can an ISBN be reused?](https://www.isbn.org/faqs_ownership_rights) No, once a title is published with an ISBN on it, the ISBN can never be used again. Even if a title goes out of print, the ISBN cannot be reused since the title continues to be catalogued by libraries and traded by used booksellers. If you'd like ISBNs to use on new self-published titles, you'll need to purchase them fresh.
