We have observed CO J=1−0 emission in 300 galaxies at 45″ resolution as part of the FCRAO Extragalactic CO Survey. The target galaxies were selected on the basis of their optical and infrared properties, such that they are either brighter than 12th magnitude in the blue, or brighter than 10 Jy at 100 μm. This data set has been used to investigate the global ratio of molecular to atomic gas mass, the fraction of galaxy mass in neutral gas, and the yield of high mass stars per unit mass of molecular gas, all as a function of morphological type and environment.
