Someone's got the wrong ISBN?

[Alessandra]

I've just been adding this book, "Narbonic 6" by Shaenon Garrity (after uploading cover images for the earlier books in the series):

Unfortunately, when I added the ISBN:

9780972693905

the database wouldn't let me save, said the ISBN was already claimed by the Yiddish version of "The Cat in the Hat":

I have triple-cchecked Ms. Garrity's book's ISBN. Both on the back cover and the index page. It's 978-0-9726939-0-5 (I've been typing it in by hand each time to make sure I'm not repeating a stupid cut-and-paste error).

What should I do?

Sometimes ISBNs are used by different books. Add your book and make a librarian note it is a book with ISBN as you sad it is.

Thank you. I have now done that.
