The following books I have been unable to locate, or have only seen for sale at prices outside my range (i.e. US$100 or more). I would appreciate a review of any of these, so I know whether it is worth continuing to look, or any information from readers on where I could find a copy in a library or elsewhere that won't cost me a fortune.
L’Armée ukrainienne by Elie Borschak in France et Ukraine, No. 1 - 2 (Paris, 1920) which I think is a journal rather than a book.
Im Kampf gegen Bolchevismus. Die Kämpfe des 2. Garde-Reserve-Regiments zum Schutz der Grenze Ostpreussens Jan - Nov 1919 by Karl von Plehve (or Plehwe) (Berlin, 1926)
The Polish-Soviet Russian War 1918-1920, being the report of the German General Staff on the war, is now in the US Library of Congress. I do not know if it was ever translated or only remains in the original German.
Armenian victories at Khznavous and Sardarabad on May 23, 1918 : and program for re-establishment of independent and neutral state of Armenia by Arthur A. Ayvazian
I can be contacted here if anyone can advise about these texts.
