Abstract
The current status of theoretical work and experimental analyses on power corrections in QCD for e+e- annihilation will be reviewed. Measurements of the number of active quark flavours n_f and the QCD colour factors C_A and C_F derived from QCD fits to event shape distributions at lower energies and LEP energies will be presented. The fits are based on O(alpha_s^2)+NLLA QCD predictions with power corrections to model hadronisation.
