Abstract: The Cosmic Infrared Background (CIB) contains the entire star-formation history of the Universe, with over half the light ever emitted from starsåÊthermallyåÊre-radiated by warmed dust. åÊHowever, determining its relationship to the optical/near-infrared-selectedåÊstar-formingåÊgalaxies that make up the optical background has proven to be incredibly cha outline state-of-the-art techniques designed to make this connection, and present the latest results from HerMES on the evolving physical properties of these infrared galaxies, including their redshift distributions,åÊclustering properties, temperatures, and luminosity densities. I will show how these properties are intimately tied to their their host galaxy stellar mass and redshift, and then summarize their implications for galaxy evolution and cosmology. åÊI will finish by presenting the Herschel Stripe 82 Survey (HerS), which was designed to leverage the rich set of ancillary data in the stripe to better answer these and other exciting questions.åÊ
