      abstract     = {The ηN final state is isospin-selective and thus provides
                      access to the spectrum of excited nucleons without being
                      affected by excited Δ states. To this end, the world
                      database on eta photoproduction off the proton up to a
                      center-of-mass energy of E ∼ 2.3 GeV is analyzed,
                      including data on differential cross sections, and single-
                      and double-polarization observables. The resonance spectrum
                      and its properties are determined in a combined analysis of
                      eta and pion photoproduction off the proton together with
                      the reactions πN → πN, ηN, KΛ and KΣ. For the
                      analysis, the so-called Jülich coupled-channel framework is
                      used, incorporating unitarity, analyticity, and effective
                      three-body channels. Parameters tied to photoproduction and
                      hadronic interactions are varied simultaneously. The
                      influence of recent MAMI T and F asymmetry data on the eta
                      photoproduction amplitude is discussed in detail.},
