We discuss polarization of gravitational radiation within the standard
framework of linearized general relativity. The recent experimental discovery
of gravitational waves provides the impetus to revisit the implications of the
spin-rotation-gravity coupling for polarized gravitational radiation;
therefore, we consider the coupling of helicity of gravitational waves to the
rotation of an observer or the gravitomagnetic field of a rotating astronomical
source. Observational possibilities regarding polarization-dependent effects in
connection with future gravitational wave detectors are briefly explored.
