Title: New M/L dwarfs identified in the Sloan Digital Sky Survey Early Data Release
Abstract: Spectra from the SDSS Early Data Release reveal dozens of previously unknown, late-type (spectral class M/L) dwarfs. Additional spectra have been obtained for some objects with the APO 3.5 meter telescope. Spectral types are assigned based on measurements of spectral indices and least squares fits to templates, both based on the spectral sequence of Kirkpatrick et al. 1999. Correlations between spectral type and broadband photometric colors are investigated.
