Alexander Graham Bell's notebooks capture the effort he put into designing and testing aerial possibilities. He was able to identify what worked - and what did not - through the engineering design process.
Historic American Engineering Record (HAER) collection was established in 1969 by the National Park Service, the American Society of Civil Engineers and the Library of Congress. The collection documents historic sites and structures related to engineering and industry focusing less on the building fabric and more on the machinery and processes within.
As the Senior Reference Specialist for the Veterans History Project (VHP), I work to make our collections accessible to on-site users as well as those who visit us in the American Folklife Center reading room.
