two books or two editions of the same book?

[Ria]

two versions of a book came out in 2019. one, subtitled Selected Short Writing contains fiction and nonfiction.

the other version, subtitled Selected Fiction, which also came out in 2019, has all of the short fiction from the other version, but none of the nonfiction. it has around half the pages.

as per Goodreads policy, does this count as the same book or two different books?

Those are two different books.
