Merging multiple editions

[Marc]

I apologize, I'm afraid that when I tried to add a different edition of a book I ended up created a duplicate instead.
The original listing is for the eBook version:
Canada at War, 1914-1918: A Record of Heroism and Achievement
The book I added (Original print copy) is:
Canada at War, 1914-1918: A Record of Heroism and Achievement
And it appears that there is a third version:
Canada at War, 1914-1918: A Record of Heroism and Achievement which may be a reprint version

Again, apologies for adding to the confusion.

Thanks

What I can say is the names of the authors should be entered in separate fields (there is a link add new author under the field for the author name).
By entering both authors in the same field a new profile is created with the name: Robert John Renison John Castell Hopkins

How to add multiple authors

Otherwise the editions look all valid (both ebooks have ISBN numbers). I just combined them.
