Goodreads Librarians Group discussion

https://www.goodreads.com/book/show/2... has ISBNs
seems duplicated by https://www.goodreads.com/book/show/1... without ISBNs.
But cannot merge second into first (found question when adding # pages 192 from http://www.amazon.com/Clues-Miss-Marp...)

The reason you cannot merge them is that standard librarians can only delete/merge books with 5 or less adds - the edition you were trying to remove has more than that. There is actually a thread, here, where you can request for a super to merge.

I have queued the duplicate for deletion for you, but do be aware that it might take a while to go through. :)
