ANN ARBOR, Mich., June 28, 2008 - ProQuest is significantly expanding the content of one of its most popular resources, ProQuest Historical Newspapers. The New York Tribune (1841-1922) is now available. The San Francisco Chronicle (1865-1922) will be released in July with The Baltimore Sun (1832-1922), and The Scotsman (1817-1950) digitized and available by the end of 2008.

"ProQuest Historical Newspapers has long been regarded as a staple for libraries everywhere," said Rod Gauvin, senior vice president of publishing for ProQuest. "These latest additions reflect ProQuest's commitment to continue that legacy by adding the world's most sought after newspapers and increasing usability of this already robust resource."

The Baltimore Sun, San Francisco Chronicle and the New York Tribune broaden the scope of ProQuest Historical Newspapers with news and perspectives from three cities that played key roles in the development of the United States.  The San Francisco Chronicle is an important resource for the study of westward expansion, Chinese immigration, 19th century politics, the Klondike gold rush, and the 1906 Earthquake and Fire.  The Baltimore Sun - the "people's paper" - provides a unique historical perspective on the slave trade, immigration and commerce. The Sun also featured the work of H.L. Mencken the "Sage of Baltimore" who wrote critically about American politics and culture. The New York Tribune -- one of the most significant newspapers in American history - documented the 19th and early 20th centuries from multiple and progressive perspectives.  Led by editors Horace Greeley and Whitelaw Reid, the New York Tribune helped shape 19th Century American attitudes, with bold editorials and features from such influential writers such as Margaret Fuller, Karl Marx, and Friedrich Engels.

The Scotsman, Scotland's newspaper of record since 1817, is an important expansion to ProQuest Historical Newspapers' international coverage. Considered "incendiary" and often radical, The Scotsman provided strong opinions and a record of events from the death of Sir Walter Scott to the Catholic Emancipation Bill to World War II and Scotland's relationship with England.  Further, the deep backfile makes The Scotsman a valuable resource for genealogists tracing their Scottish roots.  Users will soon be able to cross-search this daring paper with the The Guardian and The Observer, and The Irish Times to discover diverse editorial viewpoints of Scottish, British, and Irish newspapers, tracking the interwoven, sometimes strained, relationships between these countries.  

The archives of these newly added papers are cross-searchable with ProQuest Historical Newspapers, the world's largest digital newspaper archive, encompassing more than 20 million pages dating from 1764.  A core research holding in major libraries around the world, it includes such formidable newspapers as The Guardian, The Observer, The New York Times, The Wall Street Journal, The Christian Science Monitor, Los Angeles Times, Chicago Tribune, The Washington Post, Atlanta Constitution, Boston Globe, Hartford Courant, The Chicago Defender, New York Amsterdam News, Pittsburgh Courier, Los Angeles Sentinel, The New York Tribune and Atlanta Daily World.
