Should one of these records be considered as a duplicate?

[Natalia]

The author added her book without any details except for a cover and title (no format, ISBN or ASIN etc.). Then Amazon_catalog added Kindle and paperback editions with ASIN and ISBN. The first edition appeared as a separate book, so I combined all three. Now I'm unsure whether the first edition (and also the most added one) should be kept as is or marked as invalid/merged, as it lacks any details.

I'd merge the empty entry with the Kindle edition (the paperback has a slightly different cover).

Could you do it? I'm not a super-librarian and it has more than 5 members shelving.

Hi, I've now merged the duplicate into the valid Kindle.

Thank you!
