Goodreads Librarians Group discussion

Hello, There are some translated books that the publisher decided to split to two parts. what do I do in a situation like this?

I'll give example of what people did https://www.goodreads.com/book/show/6... here someone uploaded them together as an edition to the original.

https://www.goodreads.com/book/show/6...
and here someone uploaded them as an original work and not as an edition of the original.

what should I do?

If they were released as a set under one ISBN (or, if without identifier, packaged together), they can be combined with the full volume in one record.

If each volume had its own ISBN, or were released separately, they should only be combined with other vol.1 or 2, and not with the full work, and each should have its own record.
