The image on the cover is an east view of the U.S. Capitol building, circa 1866. Image courtesy the Library of Congress Prints and Photographs Division. (Editor’s note: We regret that the caption for the cover of the print version of the December 2008 issue was in error. The image is of the old Washington, D.C., city hall, now a court house, situated at Indiana Avenue and 4th Street, N.W.)
