ISBN doesn't exist?

[Sanne]

Hi everyone!
I was adding / cleaning up the books of the editor Jonckbloet and came across this one. I cannot find the ISBN (not the 13, nor the 10 digit code), nor can I find out whether the publisher P.N. Kampen ever published a (digital) edition of this book.

How can I find out whether it's a legit ebook?

It's a "Nook book" sold by Barnes and Noble:

They use their own ID codes in ISBN13-form (starting with 294), the 10 digit numbers are useless (they're not even recognized by B&N themselves) and should be removed. Usually you can find the books by a Google search for the ID (2940030223087 in this case), it's what I did here. Alternatively you can go to the Barnes and Noble site and do a search for the ID there.

Thanks so much for your help!

Just to be clear, whether or not an ISBN can currently be found elsewhere is not sufficient proof that a book's ISBN is not valid and it (or its edition) should be deleted.
