Query: Nucleon Form Factor Experiments and the Pion Cloud   The experimental and theoretical status of elastic electron scattering from
the nucleon is reviewed. A wealth of new data of unprecedented precision,
especially at small values of the momentum transfer, in parallel to new
theoretical insights, has allowed sensitive tests of the influence of the
pionic cloud surrounding the nucleon.
