The Population II radial velocity measurement programme was carried out in 1988-1993. Metal-deficient stars, components of Population II visual binaries or common proper motion stars, suspected radial velocity variables, Hipparcos programme stars are included into the observation programme. The measurements were made with the CORAVEL-type photoelectric radial velocity speedometer attached to the 1m reflector at the Mount Maidanak observatory (h=2560m, Uzbekistan). The average error of a single measurement is about 0.6km/s, but for the stars as faint as 13mag, or for extreme metal-deficient stars it drop down to 2.5km/s. 621 measurements for 164 stars are presented.
