Ground based and space based observations of galaxies is the 50 micron to 1 mm continuum band are used to identify a wide range of objects. Normal and active galaxies, radio quiet and radio loud quasars and blazars are observed. Millimeter and submillimeter wave observations of molecular lines, principally from the CO molecule show the dominant component of the interstellar medium in many galaxies and some quasars to be molecular H2 rather than atomic H I Gas. Submillimeter spectroscopy is sugggested as the dominant method for probing the gas content of galaxies.
