How do I tell is a book series is complete or ongoing?

[Nicole]

So I’m adding a lot of new fantasy series to my TBR that’s I’ve found but I don’t know how to find out if it’s a completed series or not. I look on goodreads and some series says another book is out soon, so that I know, but there are ones that don’t have much information. Like Lightlark. From what I know there is going to be a third book but it doesn’t say that on here.

Is there a website or an easy way to find out if the book series is complete?

I use Wikipedia, the author's website (they should have a list of all of their works)/social media (they usually post what they are working on and then when you can preorder the book, etc. At least the ones I follow), and Goodreads.
I don't use these, but there is 'fantastic fiction' and 'what should I read next.'
You can try Publishers Weekly and Shelf Awareness, but I think these are more like what is coming up, not what is already out. Hope this helps!!

I use fantastic fiction. If you search the author’s name, some will actually have their own websites.

Sometimes the publisher's website can be helpful for series/upcoming publication information for any new books in the series. A lot of library online catalogs will have links in their records to all the books in a series (and numbering order) when you search for one of the titles of the series.
