We present UBRI photometry and spectra for 60 quasars found within 1 deg 2 centered on the J0053+1234 region, which has been the subject of the Caltech Faint Galaxy Redshift Survey. Candidate quasars were selected by their ultraviolet excess with respect to the stellar locus and confirmed spectroscopically. The quasars span a wide range in brightness (17.5 < B < 21.6) and redshift (0.43 < z < 2.38). These new quasars comprise a grid of absorption probes that can be used to study large-scale structure, as well as the correlation between luminous galaxies, nonluminous halos, and Lyα absorbers in the direction of the deep pencil-beam galaxy survey. Spectra of 14 emission-line galaxies found using the same technique are also presented.
