In the Library: The Richter Archive at 75

In celebration of the 1943 arrival of the George M. Richter Archive of Illustrations on Art—the founding collection of 60,000 photographs that formed the nucleus of the department of image collections—this installation presents the history and development of the photographic archives of the National Gallery of Art. The initial gift has evolved into one of the largest collections of images of art and architecture in the world with over 15 million images ranging from daguerreotypes to digital files.
