Spectral Variability of Quasars in the Sloan Digital Sky Survey. I. Wavelength Dependence

SDSS repeat spectroscopic observations have resulted in multiepoch spectroscopy for 62500 quasars observed more than 50 days apart. From this sample, calibrating against stars observed simultaneously, we identify 315 quasars that have varied significantly between observations (with respect to assume...
