Goodreads Librarians Group discussion

I'm running across an awful lot of ebooks with isbn13 978######### numbers saying they are nook editions. Aren't only editions with the bnid 294######### numbers in the isbn13 field the only nook editions?

I was told on another thread that for nook books that the format was always ebook . Never in the format field (no clicking "other" and typing in nook edition even if that does make it show nicely when combining books).

(Nook edition could be specified in the edition field.)

Is there a "proper" capitalization of "nook edition"? (I see edition capitalized all kinds of ways in phrases in edition field so just assumed that did not matter; on the nook itself the font used makes it a bit hard to tell anyway). Rather than assume I thought I would ask (some Barnes and Noble menus show it in all caps but I actually don't like shouting anything on book data pages.)
