AB  - The precise knowledge of the QED initial state corrections is of instrumental importance in studyinghigh luminosity measurements in e<sup>+</sup>e<sup>−</sup> annihilation at facilities like LEP, the International Linear ColliderILC, CLIC, a Giga-Z facility, and the planned FCC_ee. Logarithmic corrections of up to O(α<sup>6</sup> L<sup>5</sup>) arenecessary with various subleading terms taken into account. This applies to both the inclusive measurementof processes like e<sup>+</sup> e<sup>−</sup> → γ<sup>*</sup>/Z<sup>*</sup> and also the forward-backward asymmetry. As has been shownrecently, techniques from massive QCD, such as the computation of massive on-shell operator matrix elements canbe used for these calculations. We give an introduction to this topic and present both the calculationmethods and the numerical corrections having been reached so far.
