  We observed stars with variable radial velocities to determine their
spectroscopic orbits. Velocities of 132 targets taken over a time span reaching
30 years are presented. They were measured with the correlation radial velocity
spectrometers (1913 velocities) and the new VUES echelle spectrograph (632
velocities), with typical accuracy of 0.5 and 0.2 km/s, respectively. We
derived spectroscopic orbits of 57 stars (including 53 first-time orbits),
mostly nearby dwarfs of spectral types K and M. Their periods range from 2.2
days to 14 years, some of those are Hipparcos astrometric binaries. Comments on
individual objects are provided. Many stars belong to hierarchical systems
containing three or more components, including 20 new hierarchies resulting
from this project. The preliminary orbit of the young star HIP~47110B has a
large eccentricity e=0.47 despite short period of 4.4 d; it could be still
circularizing. Our results enrich the data on nearby stars and contribute to a
better definition of the multiplicity statistics.
