Maryland Primary Resources
Baltimore Museum of Industry
The collection most used is the BGE Collection, which consists of about 80,000 photo sets taken as part of that company’s daily operations from the late 1920s through 2001. These pictures of Baltimore and the surrounding region show the changing commercial, cultural, and physical landscape of the region. Through the generous support of BGE, Constellation Energy, and Exelon, BMI is working to digitize the BGE Collection as a valuable historic resource. Currently about 10,000 of the images are available online.

The collections document achievements in architecture, engineering, and landscape design in the United States and its territories through a comprehensive range of building types, engineering technologies, and landscapes, including examples as diverse as the Pueblo of Acoma, houses, windmills, one-room schools, the Golden Gate Bridge, and buildings designed by Frank Lloyd Wright. Administered since 1933 through cooperative agreements with the National Park Service, the Library of Congress, and the private sector, ongoing programs of the National Park Service have recorded America's built environment in multiformat surveys comprising more than 556,900 measured drawings, large-format photographs, and written histories for more than 38,600 historic structures and sites dating from Pre-Columbian times to the twentieth century
