I looked up some Donne texts in the library, in my search for one or two appropriate sermons, and was sort of surprised to see the first texts in the BV and BX section, and one in HV. HV?
I'm thinking PR, and he's in HV?
I figured out the BV and BX ones after only a moment; B is for philosophy and theology, specifically practical theology and Christian denominations. Practical theology? That seems like an oxymoron in a way. But then, if by "practical" it means "the practice of" or "practices of" rather than "useful in the real world," then that makes some sense.
HV is weirder. H is social sciences, but HV is social pathology, social and public welfare, and criminology.
Quick guesses as to what Donne wrote that fits into HV?
