This paper presents an extension of the Very Long Baseline Array Calibrator 
Survey, called VCS2, containing 276 sources. This survey fills in regions 
of the sky that were not completely covered by the previous VCS1 calibrator 
survey. The VCS2 survey includes calibrator sources near the Galactic
plane, -30 deg <  -45 deg, and VLA calibrators. The positions have been derived 
from astrometric analysis of the group delays measured at 2.3 and 8.4 GHz 
using the Goddard Space Flight Center CALC/SOLVE package. From the VLBA 
snapshot observations, images of the calibrators are available, and each 
source is given a quality code for anticipated use. The VCS2 catalog 
is available from the NRAO Web site.
