series A titlename 3
series B titlename 1
series B titlename 2
series B titlename 3
That way you can open a collection for a particular series and then see immediately what the reading order should be based on the number in the title.
If you are doing something as huge as Disc World, then be sure to use Series Name A 01
titlename to ensure that they sort in order.
