The first full year of operation following the commissioning year of the Sloan Digital Sky Survey (SDSS) has revealed a wide variety of newly discovered cataclysmic variables (CVs). We show the SDSS spectra of 42 CVs observed in 2002, of which 35 are new classifications, four are known dwarf novae (CT Hya, RZ Leo, T Leo, and BZ UMa), one is a known CV identified from a previous quasar survey (Aqr1), and two are known ROSAT or FIRST discovered CVs (RX J09445+0357, FIRST J102347.6+003841). The SDSS positions, colors, and spectra of all 42 systems are presented. In addition, the results of follow-up studies of several of these objects identify the orbital periods, velocity curves, and polarization that provide the system geometry and accretion properties. While most of the SDSS discovered systems are faint (greater than 18th magnitude) with low accretion rates (as implied from their spectral characteristics), there are also a few bright objects that may have escaped previous surveys due to changes in the mass transfer rate.

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.”
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.”
SDSS unveils a population of intrinsically faint cataclysmic variables at the minimum orbital period (2009, background): “In a series of earlier papers, we have explored the properties of individual SDSS CVs (e.g. Szkody et al. 2003b; Wolfe et al. 2003; Peters & Thorstensen 2005; Gänsicke et al. 2006; Littlefair et al. 2006a; Southworth et al. 2006, 2007b; Dillon et al. 2008).”
