Neutrino oscillation experiments can provide information on neutrino m
asses and mixings. Since they probe various oscillation channels, a th
ree-flavor approach is more appropriate than the usual two-family appr
oximation. We report on st detailed three-flavor analysis of all the a
vailable solar, accelerator, and reactor neutrino oscillation experime
nts. The interplay between solar and terrestrial oscillation searches
is highlighted.
