    ISBN is invalid?



      I have a unique ISBN for my ePub, and I've even registered it with Bowker Link, but when I try adding it and click "validate ISBN" it very quickly just returns "invalid ISBN".


      What is that checking exactly?


      The ISBN is 978-1-61061-000-1 and the book is Whoa Woota.
