SZ Surveys are Coming: What should we do?
J.G. Bartlett1

Galaxy clusters furnish extremely rich information on the contents and structure of our universe. The potential of galaxy cluster studies to constrain dark energy, for example, motivates a number of ambitious cluster surveys. Among these, surveys based on the Sunyaev-Zel'dovich (SZ) effect are particularly powerful for their ability to cleanly select clusters out to redshifts z>1. Now poised to begin surveying substantial areas of sky, dedicated interferometers, bolometer cameras and the Planck satellite will soon produce large cluster catalogs that will provide a precise measure of the cosmic expansion rate over a range of redshifts and precipitate a new understanding of structure and galaxy formation. I review the science potential of these surveys and examine some issues of SZ cluster catalog construction.
