I recently reviewed (and very much admired) Pitigrilli's Cocaine, just re-issued by New Vessel Press -- and now via I learn that Hitler also had copy -- now at Harvard; see their post, Hitler's Kokain at their Modern Books and Manuscripts weblog.
(Aside: I know it's Hitler, but the fact that book was looted still brings my blood to a boil.)
