The Sloan Digital Sky Survey (SDSS) has scanned the entire region containingthe Draco dwarf spheroidal galaxy to 23rd magnitude in g*. We present a catalogof stars found in a 453 square arcminute, elliptical region centered on theDraco dwarf spheroidal galaxy. Objects in the catalog are matched with fivepreviously published catalogs. The catalog contains SDSS photometry for 5634individual objects, and also the photometry from matches to any of the othercatalogs. A comparison of the photometry between catalogs allows us to identify142 candidate variable objects. One hundred and twelve of the suspectedvariables have colors consistent with RR Lyrae variables.Comment: To appear in ApJS 14 pages, 6 figure
