    "abstract": "Eta photo- and electroproduction off the nucleon is investigated in an\neffective lagrangian approach that contains Born terms and both vector meson\nand nucleon resonance contributions. In particular, we review and develop the\nformalism for coincidence experiments with polarization degrees of freedom. The\ndifferent response functions appearing in single and double polarization\nexperiments have been studied. We will present calculations for structure\nfunctions and kinematical conditions that are most sensitive to details of the\nlagrangian, in particular with regard to contributions of nucleon resonances\nbeyond the dominant $S_{11}$(1535) resonance.",
