Query: Lack of accuracy

This book is not carefully researched. In one reference, on page 102, he refers to Soviet President Yakov Sverdlov. He states his original name was "solomon" which is untrue, and was propaganda generated by Antisemitic literature. He also states that Yakov was 44 when he died. He was 33. He was my great-grandfather, so, I am intimately familliar with his history. I found it offensive and odious that this scholar claims to present misinformation in the guise of historical truth. I would therefore be extremely dubious of his other findings.
