The US Library of Congress and its gargantuan collection never cease to amaze me.
The Panoramic Photograph Collection contains approximately four thousand images featuring American cityscapes, landscapes, and group portraits. These panoramas offer an overview of the nation, its enterprises and its interests, with a focus on the start of the twentieth century when the panoramic photo format was at the height of its popularity. Subject strengths include: agricultural life; beauty contests; disasters; engineering work such as bridges, canals and dams; fairs and expositions; military and naval activities, especially during World War I; the oil industry; schools and college campuses, sports, and transportation.
