#### Review: A Guide to Feynman Diagrams in the Many-Body Problem

User Review - Pia Jensen - GoodreadsWell, I actually only used this book as second literature in a single course, but it was great for looking up things, and to get a second opinion on different diagrams. Apart from that, I loved the typesetting in this book - it just looks great, even though it's so old. Read full review
