These proceedings will contain both general reviews on particle physics, astrophysics and cosmology and detailed discussions on some specific topics. Particular emphasis is put on: (i) physics and instrumentation in solar neutrino experiments (Chlorine, SAGE, GALLEX, SNO, Borexino, Iodine); (ii) present status and prospects of underwater and Antarctic experiments (Baikal, DUMAND, AMANDA, Nestor/SADCO, NEVOD); (iii) cosmic rays and cosmic ray neutrinos (high energy muons underground, atmospheric neutrinos, supernovae neutrinos); (iv) experiments on neutrino masses and mixings; (v) searches for dark matter and double beta decay.
