"The USDA Census of Agriculture Historical Archive is a collaborative project between Albert R. Mann Library at Cornell University and the National Agricultural Statistics Service (NASS) of the U.S. Department of Agriculture.
The site serves as a public archive of Census publications published prior to 1987. These publications are primarily scanned print material now available in PDF format."
These are digital copies of the US agricultural census publications beginning with the 1840 Census. There is some search capability.
