Abstract
I briefly review three topics of recent interest concerning power corrections, renormalons and Sudakov resummation: (a) corrections to event shape observables in annihilation, (b) power corrections in Drell-Yan production and (c) factorial divergences that arise in resummation of large infrared (Sudakov) logarithms in moment or `real' space.
