@Dr Ohh
I was going to post saying 'Don't ever' put series in
( ) as part of a title field.
I decided to test before I posted, least I wear (
more) egg.
With just the (
root) Title and author filled in
My very
first test case returned the title as
title (series) 
*root title = stripped of series and subtitle
eg.
War World: Death's Head Rebellioneg
eg. ABC
an Xyz Mystery
I strip in most case (there are always exceptions
1636: The Devil's Opera or Man-Kizn Wars XIV)
