Goodreads Librarians Group discussion

Hi. I've been trying to add a Turkish book published in 2015 with ISBN 9786053201298. When I try to create the book, I receive the warning below:

Isbn is taken by an existing book with the title "Eğitimde Özelleştirme" in 'Deleted' status. If you believe this is an error please double-check your data, then check the Goodreads Librarians group. ISBNs are optional so you can also add this book without an ISBN.

Isbn13 is taken by an existing book with the title "Eğitimde Özelleştirme" in 'Deleted' status. If you believe this is an error please double-check your data, then check the Goodreads Librarians group. ISBNs are optional so you can also add this book without an ISBN.

How should I proceed?

This is a known bug. You can click on the link to the book (it's in the error message) and change the status to "Public".
