3-in-1 in edition field

[Alex]

"3-in-1" is not something we'd put in the edition field, right? That's information for the description field, isn't it? Question apropos of this:

Honestly I never thought of that. I think it would be good to show in the description the different titles it has, if you can find it.
This book has these titles:
The Costarella Conquest
The Hot-Blooded Groom
Inherited: One Nanny

I have another question to add onto Alex, is stuff like Silhouette Desire, Blaze, Passion etc in Mills & Boon/Harlequin books considered series that needed to be added in the title whenever editing the books?
For example:
https://www.goodreads.com/book/show/2...
Or should it be placed in the edition field?

no, those are imprint numbers and should be moved into the edition field.

also, i'd agree with Alex, 3-in-1 is not an edition, it's a description of the book's contents. You can also include the full titles of books within an omnibus in the title field, like so:

Omnibus Blah: The Costarella Conquest / The Hot-Blooded Groom / Inherited: One Nanny

If the omnibus itself has a name, I typically don't bother adding the individual book titles to the title field (although I will put them in the description field) because it makes book titles pretty unwieldy. However, many omnibuses don't have names, in which case the example above would be correctly titled

The Costarella Conquest / The Hot-Blooded Groom / Inherited: One Nanny

Okay perfect, I'll move the imprint numbers to the edition fields then. Thanks!

Ah thank you both for the advice and guidance, making suggested edits! :)
