The ability to cross-search the archives of two major British newspapers with ProQuest's existing American historical newspapers provides researchers with contrasting  perspectives on key international events, such as World Wars I and II, the Middle East peace process, and the terrorist attacks in the United States September 11, 2001.  Researchers will be able to compare news, political cartoons, and editorials about the same events in both American and British newspapers.

"The vivid and fearless reporting by both newspapers has set journalistic standards not only in the UK, but also worldwide," said Rod Gauvin, Senior Vice President of Publishing for ProQuest.  "Indeed, globally many rely on the Guardian and The Observer for unbiased, thoughtful reporting on events in their own country. The addition of these two major British newspapers will propel ProQuest Historical Newspapers into a truly international news publication program, giving researchers comprehensive information that can be found easily from a single starting point."

Gerard Baines, Head of Syndication & Rights, Guardian News and Media said,  "the launch of the archive will revolutionise the way in which users are able to access our historic content, whether for academic research or personal interest. Olive Software has proven to be a fantastic technology partner fulfilling the huge task of digitising the entire archive in less than 12 months. We are also thrilled to be working with ProQuest, the world's largest distributor of digitised newspaper archives."  

The Guardian's and The Observer's archive will be cross-searchable with ProQuest Historical Newspapers, the world's largest digital newspaper archive, encompassing more than 17 million pages dating from 1764.  A core research holding in major libraries around the world, it includes such formidable newspapers as The New York Times, The Wall Street Journal, The Christian Science Monitor, Los Angeles Times, Chicago Tribune, The New York Tribune, The Washington Post, Atlanta Constitution, Boston Globe, Hartford Courant, The Chicago Defender, New York Amsterdam News, Pittsburgh Courier, Los Angeles Sentinel, and Atlanta Daily World.
