The generalization of dynamical scaling to local scale-invariance is reviewed. Starting from a recapitulation of the phenomenology of ageing phenomena, the generalization of dynamical scaling to local scale transformations for any given dynamical exponent z is described and the two distinct types of local scale invariance are presented. The special case z=2 and the associated Ward identity of Schroedinger invariance is treated. Local scale-invariance predicts the form of the two-point functions. Existing confirmations of these predictions for (I) the Lifshitz points in spin systems with competing interactions such as the ANNNI model and (II) non-equilibrium ageing phenomena as occur in the kinetic Ising model with Glauber dynamics are described.
