Re: multiple books format in one page

I found that the reason for this problem is that http://schema.org/offers includes CreativeWork as its domain, while http://schema.org/itemOffered does only include Product in its range.

I will file an issue for that, but it is not clear to me whether we should simply include CreativeWork in the range of itemOffered. Using multi-typed entities properly would be a cleaner approach.

So currently, you have to use Book -> offers -> Offer for books; Offer -> itemOffered -> Book does not work in Google as of now.
