A Gift From Earth, an early Larry Niven novel. I'm a big fan of Nivens, having read most of his solo novels along with many of his collaborative efforts, but for some reason this book slipped past me.
Stalinism As A Way Of Life by Lewis Siegelbaum & Andrei Sokolov. A collection of all kinds of documents from Russia mainly from the 1930s. Siegelbaum said they tried to get a very eclectic range of documents as far as their demeanor and what they were talking about.
