Lacking young stellar clusters and luminous OB stars, Taurus hosts a distributed mode of low-mass star formation that has proven particularly amenable to observational and theoretical study. In 2005, our team mapped the central 30 square degrees of the main Taurus cloud using the IRAC and MIPS cameras on the Spitzer Space Telescope. Next spring, we will map an additional 14 square degrees of Taurus with Spitzer. Together, these images will form the largest contiguous Spitzer map of a single star-forming region (and any region outside the galactic plane). Our Legacy team is currently generating re-reduced mosaics and source catalogs, which will be available to the community in 2006 and 2007. The Spitzer survey is a central and crucial part of a multiwavelength study of the Taurus cloud complex that we have performed using XMM, CFHT, and the Sloan Digital Sky Survey. The seven photometry data points from Spitzer allow us to characterize the circumstellar environment of each object, and, in conjunction with NIR photometry, construct a complete luminosity function for the cloud members that will place constraints on the initial mass function. We present a preliminary catalog of several hundred thousand IRAC and thousands of MIPS sources. Initial results from our study include new disks around brown dwarfs, new low luminosity YSO candidates, and new Herbig-Haro objects.
