As long as it doesn't happen often, just add another copy of the same book, for the other series.
I try to use the biggest series in published order to avoid getting headache after too much imbibing and rapid application of head to desk.
I have just one Pern series: "Dragonriders of Pern". All(?) of the Pern books in published order. 26 books. Most by Anne. Some by Todd and Gigi.
