Abstract: We present full-polarization VLBA images of 1665 and 1667 MHz OH masers toward massive star-forming regions. We discuss the significance of circular and linear polarization fractions as well as the alignment of linear polarization relative to source features. Magnetic fields deduced from Zeeman splitting suggest organized field structures with at most one line-of-sight field direction reversal. The magnetic field in a subregion of W75N appears to be aligned along the collinear arrangement of maser spots.
