It is shown that cool UV accretion disks, if present in active galactic nuclei, can be sources of line-driven winds. Subcritical disks are shown to be capable of producing winds optically thin in the continuum, which are accelerated by radiation pressure in lines (i.e., by absorption and scattering...
