A.L. Fetter and J.D. Walecka | Quantum Theory of Many-Particle Systems | QC174.5.F43 1971 | Classic text, but pre-path integrals. Now available in an inexpensive (about $20) Dover reprint. Get it! |

J.W. Negele and H. Orland | Quantum Many-Particle Systems | QC174.17.P7 N44 1988 | Detailed and careful use of path integrals. Full of good physics but most of the examples are in the problems, so it can be difficult to learn from. |

N. Nagaosa | Quantum Field Theory in Condensed Matter Physics | QC174.45.N27 1999 | Recent text, covers path integral methods and symmetry breaking. |

A.M. Tsvelik | Quantum Field Theory in Condensed Matter Physics | QC174.45.T79 1995 | [02/12/03: Now available!] |

M. Stone | The Physics of Quantum Fields | QC174.45.S79 2000 | A combined introduction to quantum field theory as applied to particle physics problems and to nonrelativistic many-body problems. Some very nice explanations. |

R.D. Mattuck | A Guide to Feynman Diagrams in the Many-Body Problems | QC174.5.M34 1967 | This is a nice, intuitive guide to the meaning and use of Feynman diagrams. The second edition is from 1976, but the library may only have the older edition. A paperback version is available from Amazon (and probably elsewere) for under $11. |

N. Goldenfeld | Lectures on Phase Transitions and the Renormalization Group | QC175.16.P5 G65 1992 | The discussion of scaling, dimensional analysis, and phase transitions is wonderful. |

G.D. Mahan | Many-Particle Physics | QC176.M24 2000 | Standard, encyclopedic reference. |

P. Ring and P. Schuck | The Nuclear Many-Body Problem | QC174.17.P7 R56 1980 | Somewhat out of date, but still a good, encyclopedic guide to the nuclear many-body problem. Doesn't discuss Green's function methods much and no path integrals. |

K. Huang | Statistical Mechanics | QC174.8.H83 1987 | Excellent choice for general treatment of statistical mechanics, with good sections on many-body physics. |
