Abstract
We present classifications for 124 objects selected from the Case Low- Dispersion Northern Sky Survey. The objects were selected from the Cas e Stellar Objects (CSO) and consist of unresolved point sources having either a featureless blue continuum or emission features in their dis covery spectra. Forty-six of the objects are confirmed quasars with re dshifts ranging from 0.20 to 2.97 with a median redshift of 1.62. We f ind that the CSO list is an excellent source of bright, low-redshift q uasars. Several quasars exhibit absorption lines arising from interven ing material. CSO 118 is a bright (V similar or equal to 16.5 mag) QSO with a prominent Ly alpha forest at a redshift of 2.97. Three of the objects are either LINERS or H II region galaxies. Most of the remaini ng classifiable objects are galactic stars and we find 11 DA white dwa rfs, 1 DB white dwarf, 3 sdB stars, 1 sdOB star, and 22 sdF-G stars. T he remaining 35 objects have noisy or featureless spectra.
