New featured picture: the Library of Congress Main Reading Room in a sweep of light, shade and colour. The image was taken by Carol M. Highsmith, the notable American architectural photographer. Highsmith is donating her life’s work of more than 100,000 images, copyright-free, to the Library of Congress, which has established a rare one-person archive to house them.
