The pseudoscalar pole contribution is the dominant source of the \cal O(α3) hadronic light-by-light scattering effect in muon g - 2. We have examined this contribution taking account of the off-shell structure of the pseudoscalar-photon-photon anomaly vertex deduced from available experimental data. Our work leads to an improved estimate, -79.2 (15.4) × 10-11, for the total hadronic light-by-light scattering contribution to the muon g - 2.
