The status of halo studies using UV absorption lines is assessed. Sin absorption is essentially only seen from gas with z ≤ 1 kpc, and shows a modest flow toward the galactic disk. CIV shows diffuse absorption in general only from gas with z ≥ 1 kpc with predominantly negative velocities. Three exceptional cases of gas showing CIV absorption without absorption by neutral components are discussed. Outflowing gas has not been detected thusfar.
