  We present the second edition of the Sloan Digital Sky Survey (SDSS) Quasar
Catalog. The catalog consists of 16713 objects in the SDSS First Data Release
(DR1) that have luminosities larger than M_i=-22 (H_0=70 km/s, Omega_M=0.3,
Omega_Lambda=0.7), have at least one emission line with FWHM larger than 1000
km/s, and have highly reliable redshifts. The area covered is ~1360 deg^2 and
the redshifts range from 0.08 to 5.41, with a median value of 1.43. Each object
has positions accurate to better than 0.2" rms per coordinate, five-band
(ugriz) CCD-based photometry with typical accuracy of 0.03 mag, and information
on the morphology and selection method, in addition to radio, near-infrared,
and X-ray emission properties of the quasars, when available, from other large
area surveys. Calibrated digital spectra covering 3800-9200 Angstroms at a
spectral resolution 1800-2100, are available. This publication supersedes the
first SDSS Quasar Catalog, which was based on material from the SDSS Early Data
Release. A summary of corrections to current quasar databases is provided. The
majority of the objects were found in SDSS commissioning data using a
multicolor selection technique. Since the quasar selection algorithm was
undergoing testing during the entire DR1 observational period, care must be
taken when assembling samples for use in statistical studies. A total of 15786
objects (94%) in the catalog were discovered by the SDSS; 12,173 of which are
reported here for the first time, including five quasars brighter than i=16.0
and 17 quasars with redshifts larger than 4.5.
