Présentation de l'éditeur
The three main objectives of the book are to:
Explain the basic physics and formalism of quantum field theory
To make the reader proficient in theory calculations using Feynman diagrams
To introduce the reader to gauge theories, which play a central role in elementary particle physics.
Thus, the first ten chapters deal with QED in the canonical formalism, and are little changed from the first edition. A brief introduction to gauge theories (Chapter 11) is then followed by two sections, which may be read independently of each other. They cover QCD and related topics (Chapters 12–15) and the unified electroweak theory (Chapters 16 19) respectively. Problems are provided at the end of each chapter.
New to this edition:
Five new chapters, giving an introduction to quantum chromodynamics and the methods used to understand it: in particular, path integrals and the renormalization group.
The treatment of electroweak interactions has been revised and updated to take account of more recent experiments.

Ainsi, à condition de garder en vue ses objectifs, ce livre peut très bien convenir même pour les "théoriciens" qui souhaite acquérir une aisance avec les calculs.
Une dernière remarque : cette édition comporte de nombreuses erreurs typographiques (par exemple des indices ou exposants qui ne sont pas écrits en petit, des indices relativistes manquants, des signes mal placés, etc.) mais dans tous les cas il n'y a pas de doutes possibles quant à l'interprétation.

One thing to point out is that this text covers many more topics than Klaubers. Klauber stops at renormalizability of QED. This book continues through QCD and the electroweak theory.
I guess you could say that Klauber makes a great companion for a QFT1 course through basic QED while Mandl/Shaw will take you all the way through a first year curriculum.
The book by Mandl and Shaw is certainly easy to read. In my case I obtained some idea about how the diagrammatic techniques look in covariant form. However, many questions I had had are still left unanswered. While it is obvious that the book is out of date, and it is hard to blame the authors for that, there is no even brief overview of the field and the basic problems it faced in that period. There is no mentioning of the approaches altenative to diagrammatic techniques. In general, the book is not very systematic, but rather present more detailed solutions for several problems that the reader is assumed to be already familiar with. Therefore, I assume, the book is good only as a supplementary material for those studying diagrammatic methods for QFT.
I'm not a specialist or active in this field, but I enjoy trying to to keep up with interesting things I was led to in college. Hence perhaps I provide the ideal perspective of the perpetual student...
I have several of the other standard texts, which I have at least perused to understand their level and approach. I find Mandl and Shaw to be the best *introduction*. Here are some reasons I like it:
- It is the best book of the bunch that is both completely deep in what it covers and self-contained (but of course it strictly assumes the implicit prerequisites: core quantum mechanics and everything you are likely to have studied if you studied that).
- It focues on the canonical approach. I'm a rabid Feynman worshipper, but in my opinion the path integral approach is best left to the second pass, because it requires two hurdles: a math one-- path calculus--, and a physics one-- shifting focus to the Lagrangian approach to QM. I find the canonical approach a better continuation of core quantum mechanics, hence a better entry point. So learn to count breadth-first; and then have fun discovering you can count it depth-first too.
- The text has a thoughtful logical order of development: Spin 0, 1/2, 1... I think I see a pattern...
Lastly, it is sprinkled with really physically deep commentary on results. Eg, how to understand spin and statistics; or when they frankly describe high-k regularization (a.k.a. math fudging) as possibly modeling new real physics. This arena is both foundational and cutting-edge-- "unfinished"; I like it that they tell it as it is.
