Proof edition of a book valid or not?

[Emmy]

Just to make sure:

Is a pre-published version of a book (edition status: third proof) eligible for inclusion in the GR database or not?

ISBN-10, ISBN-13 and ASINS: not yet exists

I have not been able to find it in the lists of valid book records or non-book items.

Advance reader copies are allowed provided they can provide a photo of their own copy. Sometimes people refer to them as proofs.
