As part of the Readex, America's Historical Newspapers Series, this product offers more than 200 significant 18th and 19th-century newspapers. EAN Series II focuses on the period between 1820 and 1860, when the number of American newspapers rose dramatically. Based primarily on the newspaper collection of the American Antiquarian Society, Series II also includes titles from the holdings of the Library of Congress, the Wisconsin Historical Society and other organizations. Dates of coverage vary by newspaper. Newspapers are in the process of being digitized and added to this Series II collection. As of July 2006, 125 of the newspapers had been added. The project is expected to be completed in two years or less.
