Abstract
New, large, ground and space telescopes are contributing to an exciting and rapid period of growth in observational cosmology. The subject is now far from its earlier days of being data-starved and unconstrained, and new data are fueling a healthy interplay between observations and experiment and theory. I report here on the status of measurements of a number of quantities of interest in cosmology: the expansion rate or Hubble constant, the total mass-energy density, the matter density, the cosmological constant or dark energy component, and the total optical background light.
