Taurus hosts a distributed mode of low-mass star formation that has proven particularly amenable to observational and theoretical study. In 2005-7, our team mapped the central 44 square degrees of the main Taurus cloud using the IRAC and MIPS cameras on the Spitzer Space Telescope. These images form the largest contiguous Spitzer map of a single star-forming region (and any region outside the galactic plane). 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 photometry data points from Spitzer allow us to characterize the circumstellar environment of each object. In conjunction with the rest of the surveys (in the regions where all surveys overlap), we can construct spectral energy distributions (in the best cases) from 0.212 to 160 microns for the known population. By comparison to the color distributions of the known Taurus members, we found 300 new candidate members among the rest of the detected objects. Via spectroscopic follow-up, we have found 25-30 new likely Taurus members.
