Ground-state properties of odd-{ital A} nuclei near closed shells are calculated using self-consistent, relativistic mean-field models of baryon-meson dynamics. Contributions from {sigma}, {omega}, and {rho} mesons and the photon are included. Comparisons are made between linear and nonlinear mean-field models, and with calculations including vacuum polarization in a local density approximation. Results are given for (intrinsic) binding energies, rms radii, magnetic and quadrupole moments, currents, and elastic magnetic scattering form factors, with comparisons to other calculations and to experiment. Bulk systematics are well reproduced by the nonlinear model and, as expected, isoscalar magnetic moments in light nuclei are close to Schmidt predictions for all models. At higher momentum transfer, currents are enhanced compared to nonrelativistic single-particle predictions, in disagreement with experiment. Extensions to include pions and derivative corrections to the vacuum polarization current are discussed.
