[DONE] Duplicate ISBN?

[Cyndi Marie ☆★Audiobook Addict★☆]

https://www.goodreads.com/book/show/5...

The book in this link above is listed with ISBN 9781913076139
(Also found it on Amazon, the published website doesn't have ISBN's https://www.amazon.com/gp/product/191... )

I was filling a "Add A Book" request in this group for this book...

https://www.goodreads.com/book/show/6... ]

but they say that the ISBN is also 9781913076139.

These are different books, different authors but same publisher?
Not sure if this is enough info to added the duplicate ISBN?

Duplicate ISBN notation added to both books:

first published: https://www.goodreads.com/book/show/6...

published with reused ISBNs: https://www.goodreads.com/book/show/5...
