Merging books (both added more than 5 times)

Hi!

I just wanted to add this book to my bookshelf:
http://www.goodreads.com/book/show/16...

and saw that there are two editions listet, that are identical. One only has the ISBN 10 and the other one only the ISBN 13. I checked it out (worldcat and DNB), those really are the same. But both editions have been added more than 5 times, so I can't do the merging myself, am I right?
