摘要：
I present an overview of new observations of atomic and molecular gas in early-type galaxies, focusing on the Atlas 3D 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.
