Those books on Russia originate from the Project Gutenberg text files. I just transfered them in HTML for easier reading. The files are quite big for HTML. I am planning to add some some articles and books later.

Russia in 1919	Arthur Ransome	Gutenberg Progect	This is an account of the author of Swallows and Amasons about his trip to the Russia in Civil War. Quite unexpected revelation.
Russia	Donald Mackenzie Wallace	Gutenberg Progect	Very thorough book on Russia from the ancient days up into the beginning of the 20th century. Good reading. Lots of facts. But it is very big... The first edition published in 1877. This one was published in 1905.
