  The Pulkovo Compilation of Radial Velocities (PCRV) has been made to study
the stellar kinematics in the local spiral arm. The PCRV contains weighted mean
absolute radial velocities for 35 495 Hipparcos stars of various spectral types
and luminosity classes over the entire celestial sphere mainly within 500 pc of
the Sun. The median accuracy of the radial velocities obtained is 0.7 km
s$^{-1}$. Results from 203 publications were used in the catalogue. Four of
them were used to improve the radial velocities of standard stars from the IAU
list. The radial velocities of 155 standard stars turned out to be constant
within 0.3 km s$^{-1}$. These stars were used to analyze 47 768 mean radial
velocities for 37 200 stars from 12 major publications ($\sim80\%$ of all the
data used). Zero-point discrepancies and systematic dependences on radial
velocity, $(B-V)$ color index, right ascension, and declination were found in
radial velocity differences of the form "publication minus IAU list of
standards". These discrepancies and dependences were approximated and taken
into account when calculating the weighted mean radial velocities. 1128 stars
whose independent radial-velocity determinations were available at least in
three of these publications and agreed within 3 km s$^{-1}$ were chosen as the
work list of secondary standards. Radial-velocity differences of the form
"publication minus list of secondary standards" were used by analogy to correct
the zero points and systematic dependences in the radial velocities from 33
more publications (~13\% of the data used). In addition, the radial velocities
from 154 minor publications ($\sim7\%$ of the data used) pertaining to
well-known instruments were used without any corrections.
