You are correct about the downvoting should have just mentioned fictfact meets most of your requirements . Btw fictfact is limited to series only so if you like a particular author unless they release another book as part of series you won't be notified about it. I think the biggest problem is that series information is not part of the standard metadata for books so you can not get information from isbndb etc. And have to manually curate it. Amazon has added series metadata to its listings but they usually don't have short stories and where they belong in the series. So I would recommend giving the ability to add books to a series to users etc to your app or website. With fictfact as the number of books and series has increased the people maintaining it need crowdsourced help in adding new books and series.
