Thanks for the reply. That's pretty much what I'm doing now. I search the Barnes and Noble webpage for the book using the exact title and then publisher, search for the Nook Books edition, make sure that "Format: eBook" in listed under Product Details, and then replace the ISBN in Calibre with the one listed under Product Details. I then disable all other metadata plugins and refresh the metadata and cover. Works perfectly, just requires manual effort for each book.
I just thought that if the plugin scraped for the format field, it could be used to further refine the search on the B&N site to get metadata specific to the electronic versions of books. Looking at the search URL on B&N though, I see that ISBN (ean) is one of the search fields returned, so I'm guessing that the plugin needs the ISBN first to find the metadata and so would not work without it?
