I briefly review three topics of recent interest concerning power corrections, renor-malons and Sudakov resummation: (a) 1/Q corrections to event shape observables in e + e − annihilation, (b) power corrections in Drell-Yan production and (c) facto-rial divergences that arise in resummation of large infrared (Sudakov) logarithms in moment or 'real' space.
