I have taken and TA-ed statistical thermodynamics and nonequilibrium statistical mechanics and have found Robert Zwanzig's book to be the best introduction to the nonequilibrium side of things. Clarity is the goal here, without the detail of Kubo's Stat. Phys. II, and MUCH clearer than the latter chapters in McQuarrie. However, a student will get much more from this book if he or she has at least some background in quantum mechanics and, needless to say, in statistical thermodynamics.
Without getting into much detail, Zwanzig focuses on the fundamental concepts in a clear exposition. If you are taking yourt first course in nonequilibrium stat mech, this is the book you should buy. If, however, you have some reasonable experience with the subject, this book is not worth as much, since it is designed to be pedagogical. In that case, Van Kampen's Stochastic Processes in Physics and Chemistry is best.
