  We present a model-independent method for determining anomalous gauge boson
couplings from ongoing and future e^{+}e^{-} -> W^{+} W^{-} experiments. First
we generalize an already existing method, which relies on the study of four
observables constructed through appropriate projections of the unpolarized
differential cross-section. In particular, we retain both linear and quadratic
terms in the unknown couplings, and compute contributions to these observables
originating from anomalous couplings which do not separately conserve the
discrete C, P, and T symmetries. Second, we combine the above set of
observables with three additional ones, which can be experimentally obtained
from the total cross-sections for polarized final state W bosons. The resulting
set of seven observables may provide useful information for constraining, and
in some cases for fully determining, various of the possible anomalous gauge
boson couplings.
