  We present results of multifrequency polarimetric VLBA observations of 34
compact radio sources. The observations are part of a large survey undertaken
to identify CSOs Observed in the Northern Sky (COINS). Compact Symmetric
Objects (CSOs) are of particular interest in the study of the physics and
evolution of active galaxies. Based on VLBI continuum surveys of ~2000 compact
radio sources, we have defined a sample of 52 CSOs and CSO candidates. In this
paper, we identify 18 previously known CSOs, and introduce 33 new CSO
candidates. We present continuum images at several frequencies and, where
possible, images of the polarized flux density and spectral index distributions
for the 33 new candidates and one previously known but unconfirmed source. We
find evidence to support the inclusion of 10 of these condidates into the class
of CSOs. Thirteen candidates, including the previously unconfirmed source, have
been ruled out. Eleven sources require further investigation. The addition of
the 10 new confirmed CSOs increases the size of this class of objects by 50%.
