Review of alpha-s Measurements
  Determinations of alpha_s are reviewed. Current results are limited to a precision of around 3-20%, largely by theoretical uncertainties. All measurements are consistent with a `world average' value of 0.118 +- 0.005 and there is no evodence of any discrepancy between `low-Q^2' and `high-Q^2' results.
