Siunnerberg, Putevoditel' po Shanxaiu - The Guide to Shanghai, Shanghai, Russkoe knigoizdatel'stvo i tipografia komiteta obshchestvennoi pomoshchi v Shanxae, 1919. The map actually does not reflect the actual extension of the foreign settlements in 1919. In particular, the French Concession is shown (colored section) under its pre-1914 extension. The map is centered on the central districts of the two settlements.
