Footnote.com
http://www.footnote.com/

With access to well over 70 million documents, Footnote.com is quite the historical treasure trove. Footnote has partnerships with The National Archives, the Library of Congress, and other institutions. The whole endeavor started in 1999 (when it was known as iArchives), and today the site features interactive historical time lines, facts, and thematic collections. Visitors should just go ahead and type a term into their search engine to see what shows up, and if they have a temporal bent they can explore by historical era. The site also includes “Footnote Pages”. Here visitors can use over 80 million pages of US government data to learn about local history, family history, or just about anything else. Also, visitors can use the site to browse pages created by other users. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
