Abstract: Spectra from the Sloan Digital Sky Survey (SDSS) Early Data Release (EDR) reveal 645 late-type (spectral type M and L) dwarfs. Additional SDSS spectra have been obtained of 34 L dwarfs from SDSS data not contained within the EDR. Stars were assigned spectral types from the spectral sequence of Kirkpatrick et al. (1999) using measurements of spectral indices and least squares fits to templates. Correlations between spectral type, optical (SDSS) and infrared (2MASS) colors are investigated.
