  Recent developments in bremsstrahlung from electrons colliding with atoms and
nuclei at energies between 0.1 MeV and 500 MeV are reviewed. Considered are
cross sections differential in the photon degrees of freedom, including
coincidence geometries of photon and scattered electron. Also spin asymmetries
and polarization transfer for polarized electron beams are investigated. An
interpretation of the measurements in terms of the current bremsstrahlung
theories is furnished.
