In 2003, Dover Publications reissued Quantum Theory of Many-Particle Systems as an unabridged, corrected republication of the original. This is the "new" version physicists refer to. The Dover edition is superior because:

Quantum Theory of Many-Particle Systems by Alexander L. Fetter and John Dirk Walecka is widely considered the "gold standard" for graduate students making the leap from basic quantum mechanics to professional research in many-body physics. Since its original 1971 publication, it has provided a unified, self-contained bridge to the complex literature of condensed matter and nuclear physics.

It treats nuclear physics and solid-state physics under the exact same mathematical umbrella. Amazon

: The definitive framework for summing infinite subsets of diagrams to calculate a particle's self-energy ( Σcap sigma 3. Finite-Temperature Formalism (

Websites like LibGen, Sci-Hub, and various Russian math-physics archives host scanned copies. While a search for "fetter walecka quantum theory of manyparticle systems pdf" will yield these links instantly, be aware:

Before this text, Feynman diagrams were primarily the domain of high-energy particle physics. Fetter and Walecka were instrumental in bringing these visual and computational tools into the condensed matter realm. They provide a rigorous derivation of Feynman diagrams, Dyson’s equation, and the concept of the self-energy. Fetter and John Dirk Walecka is widely considered
