Field Theory; The Renormalization Group and Critical Phenomena
"Recommended as the core text for any introductory course on field theory."  American Scientists (USA)  "There are only very few textbooks on the intermediate level, and the first edition of Amit's work has been a very useful one. The second edition with a detailed exposition on finite size scaling, universality and the critical behavior with several coupling constants promises to be a valuable tool in the library of many physicists."
