Beevor, the author, has been criticized for cherry picking or even ignoring Russian sources in many of his works. Additionally, this was written in 2002 and many unofficial yet contemporary sources, including video, has been found in the intervening 19 years since he wrote the book. Felton, the author of the video I posted, wrote that recently and used some of those sources in that video and his books.
