      abstract     = {Diffraction Anomalous Fine Structure (DAFS) combines the
                      long-range, crystallographic sensitivity of X-ray
                      diffraction with the short-range sensitivity of X-ray
                      Absorption Spectroscopy (XAS). In comparison to other
                      spectroscopic methods, DAFS can additionally distinguish
                      phases of different translational symmetry by choice of
                      momentum transfer, or isolate spectra from chemically
                      identical atoms on various Wyckoff sites of a crystal's
                      structure using crystallographic weights. The Anisotropy of
                      Anomalous Scattering (AAS) extends the concept of
                      isotropically scattering atoms to a more general case, where
                      the atom's scattering characteristics depend on the
                      polarization as well as the wavevector of the incident and
                      scattered X-rays. These can be written as tensors that
                      reflect the local site symmetries of the resonant atom.
                      Forbidden Reflection Near-Edge Diffraction (FRED) is an
                      elegant way to measure AAS by using reflections that are
                      extinguished in the special case of isotropically scattering
                      atoms. They can only be observed due to the non-isotropic
                      contributions at photon energies in the vicinity of an
                      absorption edge where electronic transitions occur.
                      Combining the site selectivity of DAFS with the information
                      accessible through AAS allows probing the short-range order
                      and local orbitals of selected atoms in a crystal structure
                      of a chosen phase. The present condensed review gives a
                      brief overview on the pioneer work, the theory and
                      sensitivities as well as selected recent applications of
                      these powerful and promising Resonant X-ray Diffraction
                      (RXD) methods. Additionally, some recent work of the authors
                      is included exemplarily for the model structure rutile TiO2
