  We report on a new measurement of the luminosity function (LF) and mass
function (MF) of field low-mass dwarfs using Sloan Digital Sky Survey (SDSS)
photometry. The final catalog is composed of ~15 million low-mass stars (0.1
Msun < M < 0.8 Msun), spread over 8,400 square degrees. Distances to the stars
are estimated using new photometric parallax relations, constructed from ugriz
photometry of nearby low-mass stars with trigonometric parallaxes. The LF is
measured with a novel technique, which simultaneously measures Galactic
structure and the stellar LF. The resulting LF is compared to previous studies
and converted to a MF. The MF is well-described by a log-normal distribution,
with Mo = 0.27 Msun.
