Abstract  In the four years since the Sloan Digital Sky Survey (SDSS) began operation, over 100 new cataclysmic variables (CV) have been found. Among these are many interesting systems, including eclipsing, pulsating, and magnetic CVs. A comparison of the statistics emerging from the observed period distribution of the SDSS compared to past surveys shows many more short period systems, consistent with less selection bias based on brightness. Opportunities for observations with ongoing XMM and HST projects are presented.
