Founded in 1953 by Pierre S. du Pont as the Longwood Library and merged with the Hagley Museum in 1961, the library houses an important collection of manuscripts, photographs, books, and pamphlets documenting the history of American business and technology. It's main strength is in the Middle Atlantic region but includes business organizations and companies with national and international impact.

The library's 196,000 volumes and 12,000 microforms include books and serials, pamphlets, maps and atlases, city directories, theses, government documents, company annual reports, stockholder and employee magazines, advertising literature, public relations pieces, a collection of more than 20,000 trade catalogs, guidebooks and catalogs for the great international expositions, and the Guttman Collection of pyrotechnics. Its 25,000 linear feet of manuscript contain the records of more than 1,000 firms and the entrepreneurs who build them, as well as the records of national business organizations. Noteworthy collections include the business and personal papers of the Du Pont Company and family, the Philadelphia and Reading and Pennsylvania Railroads, the Sun Company, Bethlehem Steel, the Philadelphia National Bank, Sperry-Univac, and the Sperry Gyroscope Company. Pictorial collections ranging in size from one image to more than 100,000 include formats from daguerreotypes to Polaroid prints, lithographs and engravings, and videotapes.
