The problem of evaluating Feynman integrals over loop momenta has existed from the early days of perturbative quantum field theory. This work characterizes the methods, in particular those used for sophisticated calculations, and illustrates them with numerous examples, starting from very simple ones and progressing to nontrivial examples. «
