OP, Hasselback's categories are only vaguely useful and not at all applicable to what you are looking for, I think. First, no where are teaching and research categories separated there, so quant could mean many things, including a prof who researches capital markets or who teaches statistics. Also, since the informations in the directory comes from departments and not individuals, it is riddled with errors - most info comes from the dept secretary, honestly.
Octoprof, thanks! With your advice, I now understand that I'm attempting to use a tool (the accounting doctorate listings) in a way that isn't very helpful to my goals. I'll pursue the journal/book author method recommended by everyone and revisit the doctorate listings later when I want to learn more about an individual school.
