Volume I is on theoretical foundations, QED, and Weinberg’s text is also a (perhaps the) cornerstone of QFT studies in the philosophy of science. In an ideal world, this FT question above should be merged with "Peskin's QFT Book: Solutions to Problems" is a comprehensive guide that provides solutions to the problems presented in the textbook "An Introduction to Quantum Field Theory" by Michael E.
