If you have Campbellian interests, I highly highly recommend TV Tropes. You’ll go much further than Campbell or his interpreters or Jung) as:
a) You’ll find they’ve all been in common use for decades now
b) You’ll recognize it when you see it..
Takes a lot of the “woo” out of Jung and Campbell and their interpreters, but it really ties it all together as a “‘common personality expectations” for fiction.
