Currently reading it and having good time... Glad to see find new diary entries, that's the most valuable. The commentaries are thoughtful. I nevertheless would have some observations; they perhaps will of any help for a second edition (I wish it for you!) and for other readers!
26th August 1914: "Sh" is probably not Voronov, but Shvedov, Alexander Konstantinovitch, "Shurik". My opinion.
The "K." Olga is writing about at the end of 1914 and beginning of 1915 (for example 1st January 1915) is not Kiknadze. It is most likely Karangozov, another caucasian guy. Reading the diary for those period, it is evident that Olga was not indifferent to this young officer, though nothing like a Voronov, or a Shakh-Bagov.
P. 23, 21st February 1915: Andrei is not Andrei Vladimirovitch, but Andrei Alexandrovitch, son of Ksenia A. and Alexander Mikhalovitch. (I now understand why Alexander III did not want allow KR call one of his son Andrei: a pity Nicolas II did not continue his father's line on the name question in the Romanov family!)
In the introduction. Nicolas and Alexandra did not make Alexander Palace their permanent residence since 1898. Actually, they lived in the Winter Palace from january to march or april. Then in Tsarkoe Selo till june, then in Peterhof. In the middle of August they go for travel: Crimea, Europa, Poland (Spala and other places for hunting). October or november: back to Tsarskoe, and so on.
The Alexander Palace became their main residence only after 1905.
