The accurate calculation of atomic spectra, including radiative corrections, is one of the rather challenging tasks in theoretical physics. The entire formalism of quantum (gauge) field theory, augmented by the difficulties of the bound-state formalism, is needed for an accurate understanding of the relevant physics at the level of current high-precision spectroscopy. In this thesis, several calculations in this area are described in detail. Investigations on large-order perturbation-theory effects (and predictive limits of perturbation theory) supplement these investigations. In the context of applications, numerical algorithms for the acceleration of the convergence of series are discussed.
