ADC_Keywords: Bibliography; Clusters, open; Radial velocities 

Description:
    This second part of the bibliography contains 6504 individual
    radial velocities for 774 stars in 78 open clusters. It is devoted
    to NGC and IC open clusters. The first part (Mermilliod J.-C.,
    1979, Bull. Inform. CDS 16,2; catalogue III/55/) contains the
    data for five nearby open clusters. The collected data have been
    found in the literature published from 1900 to the end of 1983.
    This catalog contains also unpublished data which have been 
    delivered to Mermilliod by several authors.
