Although this approach goes back to the pioneering works of Symanzik in the early 1970s and was systematized by Becchi, Rouet and Stora as early as 19

Introduction,e underline, in particular, the well established and successful applications to the gauge theories of particle interactions: QED, the standard model, QCD and supersymmetric extensions thereof. Although a quantum theory of gravity has not yet been firmly formulated, there are now hopes for a consistent field theoretical description as well [3].

Precisely the latter approach is called “algebraic renormalization” in the present book.
