An economic geography of the Ruhr, dealing with such subjects as the supply of consumer goods to the Ruhr, the industrial production of the area, its markets, the transport connections, etc. The first edition appeared in 1940, and there is no discussion of wartime developments. The bibliography contains no titles later than 1938 and the statistics are those of the latter 1930's.
