"Do Koreans really know 'Jokbo' (족보)?"

ANSWER: The real question should be: "Do Koreans, or anybody, really want to know about Jokbo (족보)?" I suspect there are very few who do.

I don't know what professors are teaching their students in Korean Studies these days, but hopefully they are not wasting too much of their students' time and money teaching them about Jokbo and other useless things. Korean Studies professors should give their students the background and language skills needed to learn about that kind of stuff if they want, but they shouldn't bore them with too many details.
