Looking for primary sources in the history of invention? The Lemelson Center has created this database of invention, technology, and science-related collections located in archives, libraries, historical societies, and museums in the United States and Canada. The Lemelson Center does not maintain its own archive, but serves as a clearinghouse for information on sources.
When you select a collection from the list below, you will open a new page with a logo at the top that indicates whether the collection is held by the Smithsonian or elsewhere.
Collections with the color logo are available for research at the Smithsonian.
Collections with the black-and-white logo are not part of the Smithsonian. See listings for access information.
