Add book to existing series

[Rebecca]

I made a mistake and instead of adding this volume to the three that went before it in the Best Small Fictions Series made a new series with the same name.

Can someone fix it for me, or tell me how I can fix it myself?

Firstly, I do not think this will qualify as a series.
To be a series, books should have characters and/or universes in common. In the case of imprints and other non-series collections, it is common for some of these books to be published under numerous other imprints as well.

Secondly, please see instructions on series editing in Librarian Manual:

It's a set of four yearly anthologies, all with the same title but a different guest editor. The first three already existed as a series. Thanks for the link -- I've deleted the egregious extra series I made and added the 2018 volume into the right one.

Still, they should be not listed as a series, unless the stories within it have common characters or a shared universe.

Could you confirm if that's the case?
