Under LC subject search : structured heading : Nose-Surgery I can see
call number correlations to RF51 and RF451.
When I click on RF451 Restoration (which is appropriate for the book I
have in hand), there is no such number in the LC Class hierarchy.
There appears to be a gap between RF437 and RF459.2-547.
I notice that RF451 has been used 10 times in Voyager, but the most
recent record that uses it is dated 1965.
Is RF451 still valid?
