Clarification needed on anthologies and series

[Mē-chan]

I noticed that somebody added an anthology
https://www.goodreads.com/book/show/1...
to this series
https://www.goodreads.com/series/8788...

I couldn't find anything in the librarian manual, so I was wondering if one story in an anthology qualifies the book to be a part of that series or not? Or any other series for that matter if it contains short story from authors of the particular series.

I just need a bit of clarification on this.
Thank you.

Yes, if the anthology contains a story that is part of a series the anthology is added to the series. In this case, most of the stories belong to various series, so the anthology would be added to each of the series.

Ok, that explains it.
Thank you very much.
