Nonpower Expansions for QCD Observables at Low Energies
  A comprehensive review is presented of the progress made in further developing the ghost-free Analytic Approach to low-energy QCD since "QCD-97" meeting. It is now formulated as a logically closed ``Analytic Perturbation Theory" algorithm. Its most essential feature is nonpower functional expansions for QCD observables.
