RE: Written Works and Collections

But doesn’t it bother you at all that a short story which appeared in a magazine is not really a book?

That's not entirely true that Google insists on an ISBN for a Book.

In Google's world...Google knows and understands that a Book and a CreativeWork are 2 different Things.  And that there could be many CreativeWorks inside a Book, that might have an ISBN assigned or not.

Here's what you probably missed in the SDTT tool docs...
(its a shame that the SDTT tool says Required rather than tell you the full hint that is in the docs.  I would say that is a bug in SDTT that you can inform them about on their forums.

itemReviewed.isbn (Required)    Text    ISBN of the book. In cases where no ISBN exists, use sameAs (see below).
itemReviewed.sameAs (Required unless isbn is defined)   URL     URL to a page that unambiguously identifies the book. URLs to the Google Play Books page, Wikipedia page, or official website are stongly preferred.
