Neutrinoless Double Beta Decay: Present and Future
  Present status, and future plans for Double Beta Decay searches are reviewed. Given the recent observations of neutrino oscillations, a possibility to observe $\beta\beta(0\nu)$~ at a neutrino mass scale suggested by present experimental results ($m_{\nu} \approx$10-50 meV) could actually exist. The achievement of the required experimental sensitivity is a real challenge faced by a series of new proposed projects. Plans to achieve such a result are described.
