I am now in the position of possessing these books, and have been using machine translation to read the text of selected programs of interest.
They are very nice. It basically goes through all the programs which made it to hardware in great detail, and there will be stuff that is new to a Western MiG fan on pretty much every program and pretty authoritative, based on the authors' access to MiG corporate archives. There are lots of very beautiful original OKB drawings and artwork which has not been seen before, and these include early iterations and unbuilt versions of the core designs studied.
There is coverage of some projects which didn't make it to hardware, but the focus is (rightly) on the actual aircraft. Its like the old 'OKB MiG' book on steroids.
