Here may be Dragons
You may not have the Eggs in your Library yet, but the will happen.
The dreaded Unrelated Series (name. Different Author-Different Universe)
You found the Reused Title (not really, Great Authors think similarly)
Then there is the Shared Universes, Where Many Authors write books as part of the Universe. For this to even remotely sort by anything OTHER than series +Index is a pipe dream
Lets talk Series. Title sorting is counter productive.
Series is all about INDEX (the number) Think about it: The Title of Book 1 is Zoolander , Book 2 is Alpacas
Sorting by Author
s for anything other than
non-series titles is a route to madness. Go look at Fantastic Fiction for how many Authors have titles that list 'With xyz, or Include a second, third, fourth author "
Each variant sorts based upon
the ENTIRE set of names
FWIW My solution to the reused Series was to add manually after checking that tis was not the Shared Universe issue, the creating authors initials to the series name: Magic (AN)
