Readex, a division of NewsBank, publishes collections of primary source research materials. 
History.
In 1950, publisher Albert Boni, co-founder of the Modern Library, formed the Readex Microprint Corporation in New York City. Some of the companies Readex partnered with early on included the American Antiquarian Society and the Library of Congress. Early printing projects included the “British House of Commons Sessional Papers”, the “Early American Imprints, 1639-1800”, and the “English and American Drama of the 19th Century”.
In 1983, Readex was acquired by NewsBank. Since the acquisition, the company has been known primarily as NewsBank.
In the 2000s, several collections became available in searchable digital editions.
Partnerships formed in the 2000s with the Library of Congress, Dartmouth College Library, University of Vermont Libraries, and the United States Senate Library led to publication of digital editions of the American State Papers and the United States Congressional Serial Set.
In 2006, Readex launched America's Historical Newspapers, which includes Early American Newspapers, 1690-1922, and American Ethnic Newspapers.
In 2007, Readex announced a Web-based edition of the Foreign Broadcast Information Service (FBIS) Daily Reports, 1941-1996—the record of political and historical open-source intelligence for the United States government. Also developed was a digital edition of Joint Publications Research Service (JPRS) Reports, 1957-1994.
In 2008, Readex announced a partnership with the Center for Research Libraries to launch an online World Newspaper Archive.
