Abstract
A very faint spectroscopic quasar survey was undertaken in order to define the statistical behavior of the low luminosity portion of the quasar population at high redshift and to search for evidence of a decline in space density. Both slitless and multi-aperture spectroscopic observations were obtained for approximately 750 objects with B magnitudes in the range 20 < B < 24. The total number of emission line candidates found was ~ 50 and there are 5 excellent quasar candidates, 3 very probably at high redshift. In addition to the quasar candidates a number of emission line galaxies have been identified.
