Hundreds of historic newspapers have been reproduced in searchable electronic databases, such as ProQuest Historical Newspapers™, Readex’s Early American Newspapers, and Gale’s 19th Century U.S. Newspapers, which are available online by subscription and at many research libraries. Some state and local libraries have also digitized portions of their newspaper collections and have made them available online to the general public. A useful guide to early American newspapers is available on the Library of Congress’ Chronicling America: Historic American Newspapers Web pages, athttp://chroniclingamerica.loc.gov.
