3 Editions of book not coming up together (combinable)

[Jan]

The following search brings up 3 editions of the same book:
http://www.goodreads.com/search/searc...

The books are:

http://www.goodreads.com/book/show/19...

http://www.goodreads.com/book/show/12...

http://www.goodreads.com/book/show/34...
(I added the 3rd edition from my personal library)

These should be combined. While they all come up on the search but not as combinable editions.

These are clearly the same book.

How can this kind of thing be handled?

[This Is Not The Michael You're Looking For]

The problem is the author name. The author has to be identical on all books that are to be combined.

I fixed the name and combined the editions.
