The Oboler Library now offers electronic access to the Archive of Americana database. This family of historical collections contains books, pamphlets, broadsides, newspapers, government documents and ephemera printed in America over three centuries. It includes American State Papers (1789-1838), the U.S. Congressional Serial Set (1817-1994), covering the 1st through 103rd Congresses.
Our Documents Librarian, Beth Downing shares the following information with us:
The variety of information in the House and Senate committee reports might surprise you. Almost any topic you can think of is covered, from raising silk worms to the sinking of the Titanic. The early research on the American West is especially interesting and includes the reports of the original surveys made by Hayden, Fremont, and Powell as well as the Bureau of Indian Affairs documents. The early maps can be found in the U.S. Congressional Serial Set Maps database. Find these databases on the Resources by Subject / Government Documents page.
