If you are a beginner who want to learn some basic techniques such as how to write down the partition function of a Fermi system in terms of path integrals or how to calculate the Lindhard function of a Fermi gas, this is not a book for you because these results are simply quoted. If you want to learn some advanced techniques such as the details of renormalization group and how to use it to study interesting phenomena such as classical and quantum phase transitions in many-body systems, you can only find a few vague and incomplete examples in this book without any systematic introductions. About half of the book is focusing on nuclear many-body physics. As a person who is more specialized in condensed matter physics, I may not be able to judge it properly. However, as far as I can tell, many of these topics consist of only half to one page of brief descriptive introductions. I doubt that one can really learn anything useful from that. Therefore, for people who want to learn these topics, it is probably better to consult the original literature.A book that titled many-body physics is usually about techniques, and this book does not fall into that category. It may serve for some particular purposes, but in my opinion, it is neither a suitable textbook for students nor a useful reference for seasoned researchers.
