The commissioning year of the Sloan Digital Sky Survey (SDSS) has demonstrated that many cataclysmic variables (CVs) have been missed in previous surveys with brighter limits. We report the identification of 22 CVs, of which 19 are new discoveries and three are known systems (SW UMa, BH Lyn, and OU Vir). A compendium of positions, colors, and characteristics of these systems obtained from the SDSS photometry and spectroscopy is presented, along with data obtained during follow-up studies with the Apache Point Observatory and Manastash Ridge Observatory telescopes. We have determined orbital periods for three of the new systems, two show dwarf nova outbursts, and the third is a likely magnetic system with eclipses of its region of line emission. Based on these results, we expect the completed survey to locate at least 400 new CVs. Most of these will be faint systems with low accretion rates that will provide new constraints on binary evolution models.

Cataclysmic Variables from the Sloan Digital Sky Survey. II. The Second Year (2003, background): “For the field of cataclysmic variables (CVs), SDSS is able to find many new CVs, especially those with faint magnitudes that were missed in previous surveys with brighter limits (Szkody et al. 2002, hereafter Paper I).”
SDSS unveils a population of intrinsically faint cataclysmic variables at the minimum orbital period (2009, background): “The CV sample identified in the Sloan Digital Sky Survey (SDSS) (Szkody et al. 2002c, 2003a, 2004, 2005, 2006, 2007a, 2009) has the potential to overcome many of the limitations of existing samples, as it extends to fainter objects and covers a wider range in colour space than any previous optical…”
The Donor Stars of Cataclysmic Variables (2006, background): “In order of decreasing period, these systems (and their spectral type referencs) are SDSS J1702+3229 (Szkody et al. 2004), QZ Ser (Thorstensen etal.”
FIRST RESULTS FROM THE CATALINA REAL-TIME TRANSIENT SURVEY (2008, background): “Indeed of the 213 new and known CVs measured by Szkody et al. (2002; 2003; 2004; 2005; 2006; 2007) in SDSS data, only ten had (u − g) > 0.7.”

THE EVOLUTION OF CATACLYSMIC VARIABLES AS REVEALED BY THEIR DONOR STARS (2011, background): “However, Gänsicke et al. (2009, hereafter G09) recently located the period spike at Pmin 82 minutes in the Sloan Digital Sky Survey (SDSS) CV sample, which makes this discrepancy even worse.”
A Catalog of Spectroscopically Confirmed White Dwarfs from the Sloan Digital Sky Survey Data Release 4 (2006, background): “…specialized SDSS catalogs have been presented for magnetic white dwarfs (Schmidt et al. 2003; Vanlandingham et al. 2005), white dwarf plus M star binary systems (Raymond et al. 2003; Smolčić et al. 2004; Silvestri et al. 2006), and cataclysmic variables (Szkody et al. 2002, 2003b, 2004, 2005).”
