Keep an eye on this URL in February. The Library of Congress is set to launch the "General-access Phase 1 prototype" of American Chronicle—"a national, digital resource of historically significant newspapers from all the states and U.S. territories published between 1836 and 1922."
The digital collection will begin with 118,000 pages from newspapers published between 1900 and 1910 in California, Florida, Kentucky, New York, Utah, Virginia, and Washington, D.C. Over time newspapers published between the 1830s and 1922 will be added from all states and territories. Also "American Chronicle" will offer a Newspaper Directory of records for more than 125,000 newspaper titles published between 1690 and the present, along with library holdings information, acquired from OCLC WorldCat, with links to digitized page content when available. For more see http://www.loc.gov/ndnp. [Link]You can already sample the California and Utah offerings. Here also are links to the Florida, Kentucky, New York, and Virginia project pages, and to a list of the DC papers to be included.
