I'm spending today converting an essay from last semester from Chicago-style citations (favored by historians) to Bluebook-style citations (favored by legal practitioners and scholars) so I can submit it to the journal Communication Law and Policy as my chair has advised me to do.
I've sometimes joked that some towns have bad road signs because they don't want to make it easy for strangers to navigate the town. "If you was from here you'd know where you was, if you ain't then go home." Bluebook seems somewhat the same way. Why on earth would one subsititute "U. Pa. L. Rev." for "University of Pennsylvania Law Review" except to obscure and mystify things for those without training in the law?
