      abstract     = {We review the dispersion-theoretical analysis of the
                      electromagnetic form factors of the nucleon. We emphasize in
                      particular the role of unitarity and analyticity in the
                      construction of the isoscalar and isovector spectral
                      functions. We present new results on the extraction of the
                      nucleon radii, the electric and magnetic form factors and
                      the extraction of ω-meson couplings. All this is
                      supplemented by a detailed calculation of the theoretical
                      uncertainties, using bootstrap and Bayesian methods to pin
                      down the statistical errors, while systematic errors are
                      determined from variations of the spectral functions. We
                      also discuss the physics of the time-like form factors and
                      point out further issues to be addressed in this framework.},
