To view the images, point your browser to http://www.sources2go.com and select one of the available links under the Census Records category.
Images are also available for other record sets including the 1790 U.S. Federal Census (complete), War of 1812 Military Bounty Land Warrants, Chemewa Indian School, District of Columbia Naturalization Index, Record Cards of Letter Carriers of the U.S. Postal Service, and Substitute Clerk Appointments of the U.S. Postal Service.
The site provides two ways to view the images -- the Regular viewer (which is slow and requires JavaScript) and the Flash viewer (reqires the Macromedia Flash plug-in, but is really fast). If you are unable to view the images, please send a note directly to me at the email address listed in the from line.
Thanks.
