Problem with merging

[Marina]

Hi, this is my first post here. I'd like to merge two books that are the same (same edition, same language, same everything). The mistake was mine, as I wanted to add a more correct edition so I added a new one instead of correcting the old one (I wasn't a librarian then). Only problem is I can't merge them because when I go to the combine section there seems to be only one edition and not two. So, how do I correct this mistake? The ISBN of the correct edition is this: 9789608993792 and the wrong one is 9789608993. In essence, the other user has omissed some digits from the ISBN and has put the writers incorrectly in the description.

Thank you

Books need to have the same primary author to combine them. After changing the author you can combine both editions and merge the wrong edition.

Thank you, problem solved! I didn't know it had to be the primer author the same.
