  The Sloan Digital Sky Survey [SDSS] has measured an optical luminosity
function for galaxies in 5 bands, finding 1.5 to 2.1 times more luminosity
density than previous work. This note compares the SDSS luminosity density to
two recent determinations of the near infrared luminosity function based on
2MASS data, and finds that an extrapolation of the SDSS results gives a 2.3
times greater near infrared luminosity density.
