The Scientists Revolt. Edgar Rice Burroughs

"The Scientists Revolt" qualifies as a publishing curiosity. A collaboration between author Edgar Rice Burroughs (famous for Tarzan and the Martian novels, among others) and Ray Palmer (editor of numerous pulp magazines), it is a slam-bang pulp action story set in the 23rd Century, where the struggle of the intelligentsia against the proletariat has played out to rather silly results. Complete with 1920s-style archetypes (including hardboiled Irish cops), sci-fi trappings like matter transmitters, and the obligatory romance between classes, it's a truly unique product of the pulps.
