Query: Good result, but more information about the product needed

In fact I got what I wanted, but it was not so easy to be sure that I had ordered the right item. There are various editions and revisions of the book and the accompanying CDs. I already had the book but I wanted the CDs for the same edition of the book.It was only by specifying the ISBN number that I could find the right product. However the ISBN number is not actually shown on the order.
