Early-type galaxies hold important clues to how galaxies form and evolve. Their elusive interstellar medium has become revealed through several dedicated surveys, which detect an appreciable amount of interstellar medium at any phase looked at thus far and for a significant fraction of early-type galaxies in the local universe. We show results on the dust and gas properties for a sample of early-type galaxies drawn from the Herschel Reference Survey. The sample consists of early-type galaxies that are simultaneously detected in sub-millimeter and CO observations.
