Based on some of the transcript info and seminars I’ve attended, I have used the same book in several catagories – depending upon other readings upon occasion.
So, you could use Plutarch as Civics (with other books), Citizenship (possibly w/ others, though I’m inclined to leave it as is), Ancient Writings (include others like Josephus, etc. if studied), and even Personal Development (with other books)

**Edit – I see Citizenship and Personal Development as separate, though some would call them the same thing – or that C is inclusive of PD, perhaps.
