Why, Library of Congress, why would you have me shelve these two books so far away from each other?
PZ7 is supposed to be an obsolete classification for children’s literature. Obviously the person who did the LCN for Catching Fire was working under the old system. We use PZ7, though, at HNU. Give me Mocking Jay and Hunger Games (if it also needs fixing) and I’ll put them all together. We can discuss which option is best for the books: PS or PZ.
It’s helpful being followed by your cataloger.
