A very fine piece about the Ilya Murometz is in the French language magazine
Icare No.184 Les Ilya Mouromets au combat. This very big article is a translation from the Russian into French of the journal a pilot of an Ilya Mourometz :
Sergueï Nikolayevitch Nicolsky [ 1885 - 1963 ]. It is a fascinating account, illustrated with the most fabulous and sharp printed photos of the machine I have ever seen. Purchase it, or better still if you cannot read French learn it to understand the text.
Another article in the same Icare is by
Vadim Rostislavovitch Mikheev (professor in the history of science at the Academy of Science in Russia) about the historical significance of the Ilya Murometz. Again very fine and sharp photos, perhaps never seen till now in the west.
There is an excellent booklet in Russian with hosts of photos printed on not really good paper, so they do not come about very fine. This book is in series called Armada and is No.8. I got mine via internet in a Russian bookshop somewhere.
I see AGBlume already mentioned these works, so this is two times the same
