Got bored so I decided to check the books/authors.
Book #1 is written by a German who moved to South America after WWII. Fun starter.
Book #2 is from 1955, I can't imagine a Western author would have access to Soviet sources at that time.
Book #3 has one result when I google it, which is the wikipedia page you copied this from.
Article #4 is also before Soviet archives were open to the West, and is from some journal called "Slavic Review", which seems to specialize in Barry Goldwater esque psychoanalysis of Soviet leaders.
Book #5 is a collection of academic articles. Whoever added this citation does not appear to have actually read it, as the citation does not mention which article in the book is relevant.
