Incorrect ISBN

[Ruby]

I've just added "Taste of Cockroach and Other Short Stories" to GR manually, but it won't accept the ISBN. I have double-checked against the actual book and I do have the correct ISBN, however, it says that this ISBN is being used for another book with the title "The Blindfold Horse and Other Stories". The ISBN is 0909955166

I have saved Taste of Cockroach without an ISBN in the meantime. Can someone please fix the problem, or let me know how to do it?

Cheers.

This ISBN was reused, searching for it on WorldCat brought up both "Taste of Cockroach..." and "The
Blindfold Horse..."

Unfortunately, since the same ISBN number can't be used twice, there's nothing to be done here aside from adding a librarian's note stating the ISBN of your book.

It's the same idea as an alternate cover edition.
