The Recent Evolution of Early-Type Galaxies as Seen in their Cold Gas
  I present an overview of new observations of atomic and molecular gas in
early-type galaxies, focusing on the Atlas3D project. Our data on stellar
kinematics, age and metallicity, and ionized gas kinematics allow us to place
the cold gas into the broader context of early-type galaxy assembly and star
formation history. The cold gas data also provide valuable constraints for
numerical simulations of early-type galaxies.
