Multiple Book Request for Various Series

[VDY]

I have multiple requests from various books I've just added, please let me know if I should instead submit these as separate requests.

The Third Wheel
This book is part of this series.
It is not one of the main books in the series but instead a printing of all 5 stories in the series.

Roll Credits
This book is part of this series.
It is not one of the main books in the series but instead a printing of all 6 stories in the series.

The One Who Got Away and Drifting Down The Lazy River
This book is part of this series.
It is not one of the main books in the series but instead a printing of both stories in the series.

Tales of the Sun
Tales of The Moon
Finally these two. There is no existing series for them, and I'm not sure they are supposed to be in a series. The two are part of the same collection released by the publisher. The question here is really, how should the relation between these two be created? Would it be a series, or some other mechanism?

[Sandra]

First 3 done.

Do Tales of the Sun & Tales of the Moon share any characters, or universe?

[VDY]

Thank you for taking care of the first 3 and also updating the titles where needed.

The two books are fanfiction compilations centered around a different character for each. While they do share the same characters and universe (due to their nature as fanfiction) none of the individual stories in the compilations are technically in the same "fanfiction universe" as each other, so probably not a series.

Is there any other mechanism for which the two would be related other than series? They are part of the same collection/series sold by the publisher.

While researching how I should handle adding them I found mention of "Listopia" would that be the appropriate place to create this association?

[Sandra]

You could turn them into a Listopia. That would be the only option as they don't meet the criteria for a series.

[VDY]

Thank you, I've added them to a list here.

[Sandra]

Well done, VDY!
