The commissioning year of the Sloan Digital Sky Survey has demonstrated thatmany cataclysmic variables have been missed in previous surveys with brighterlimits. We report the identification of 22 cataclysmic variables, of which 19are new discoveries and 3 are known systems (SW UMa, BH Lyn and Vir4). Acompendium of positions, colors and characteristics of these systems obtainedfrom the SDSS photometry and spectroscopy is presented along with data obtainedduring follow-up studies with the Apache Point Observatory (APO) and ManastashRidge Observatory (MRO) telescopes. We have determined orbital periods for 3 ofthe new systems: two show dwarf nova outbursts, and the third is a likelymagnetic system with eclipses of its region of line emission. Based on theseresults, we expect the completed survey to locate at least 400 new CVs. Most ofthese will be faint systems with low accretion rates that will provide newconstraints on binary evolution models.Comment: 26 pages, 11 figures, 7 tables, accepted for publication in A
