Abstract
The final version of the multi-resonance, coupled-channel partial wave analysis with the significant improvement of the πN elastic S11 partial wave is presented. The need for the new, only theoretically predicted P11 resonance is pointed out. The value of the ηN S-wave scattering length is finally unambiguously established.
