Abstract:
    The Arecibo 1612MHz survey of a complete sample of color-selected IRAS
    sources with 25µm fluxes S(25)>2 Jy detected 393 OH/IR stars. A
    complementary 1667 and 1665MHz OH survey of these objects is presented
    here. Main-line masers have been detected in 238 surveyed objects: 18
    exhibit only 1665MHz emission, 220 exhibit 1667MHz masers, and 119
    exhibit both. The main lines were not detected in 159 objects.
