  The present paper describes the first results of an observational program
intended to refine and extend the existing vsini measurements of metal-poor
stars, with anemphasis on field evolved stars. The survey was carried out with
the FEROS and CORALIE spectrometers. For the vsini measurements, obtained from
spectral synthesis, we estimate an uncertainty of about 2.0 km/s. Precise
rotational velocities vsini are presented for a large sample of 100 metal-poor
stars, most of them evolving off the main-sequence. For the large majority of
the stars composing the present sample, rotational velocities have been
measured for the first time.
