Title: The Extragalactic Distance Scale Authors: Joseph B. Jensen (Gemini), John L. Tonry (Hawaii), John P. Blakeslee (JHU) Comments: 18 pages, 1 figure; contribution to Measuring and Modeling the Universe, Carnegie Observatories Astrophysics Series Vol. 2, ed. W. L. Freedman \ Significant progress has been made during the last 10 years toward resolving the debate over the expansion rate of the Universe. [...] We discuss remaining systematic uncertainties, particularly related to the Cepheid calibration, and identify where improvements are likely to be made in the next few years.
