We conservatively define the most uniform statistical sample possible, consisting of 15343 quasars within an effective area of 1622{deg}^2^ that was derived from a parent sample of 46420 spectroscopically confirmed broad-line quasars in the 5282{deg}^2^ of imaging data from SDSS Data Release 3. The sample extends from i=15 to 19.1 at z<~3 and to i=20.2 for z>~3. 2006AJ....131.2766R https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/2766 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to VII/243 : SDSS quasar catalog.
